The Bible's Bad Science
I think the intention of these lists is that you don't actually check either the science or the Bible passage cited. You're just supposed to scan down the list and marvel at how all that science could have been included in the Bible if it hadn't been written by a god. Then you conclude that you're obviously right to believe in the god your parents told you was the real one and feel that nice warm glow of self-satisfaction that comes from being right all along.

Catholic Church's Exquisite Paradox
Cardinal Reinhard Marx, "Theologically unacceptable" |
The Catholic Church in Germany, as elsewhere, faces a nightmare paradox - give up being Catholic to retain members and a degree of authority, or remain Catholic and cease having any relevance to people.
The panic spreading through the Catholic Church as it crumbles under the assault of secular Humanist ideas and becomes ever less relevant to the lives of decent, ordinary people throughout the developed world, can be judged from what's going on in Germany, where the Catholic Church is teetering on the brink of collapse.

Look What Religion Can Be Used For
After citing his own evidence-free earlier claim that the German Pilot who crashed his plane in the Alps killing all on board was a Muslim, he manages to connect this event to the Obama administration with:
A similar tragedy is, at this moment, playing out in America. The cockpit is the Oval Office which guides our country to its destination. Sitting at the controls is Barrack [sic] Hussein Obama who, according to many reports (which includes photos), also possesses sexual confusion regarding straight and gay. He executes insane decisions with what appears to be a deliberate scheme to nosedive our country into oblivion.
Obama is not clinically insane but has been specifically programmed by his Communist handlers along with his Muslim allies to take America over the cliff. He is not dumb but a very useful idiot for the Communist Party (Josef Stalin's description for those who help his cause). Obama is totally controlled as an authentic Manchurian Candidate.

An 'Intelligent Design' That Really Gets Up Your Nose
There was me thinking the 'Intelligent Designer' couldn't get any nastier when I wrote a couple of months ago about the parasitoid wasp that turns a ladybird into a zombie by injecting it with a mind-controlling virus. Now I've come across something else which surely competes with this for sheer malevolent nastiness. Of course, sheer incompetence could also explain it.
It's an amoeba which destroys the human brain, but it doesn't do it simply by eating it - that would be too simple for our malevolent 'Intelligent Designer'. It does it by making us destroy our own brain, not just because our immune system isnt fit for purpose but also because of the way our brain is fitted into our skull.
Naegleria fowleri is a species of amoeba which lives in warm, freshwater pools, normally living on a diet of local bacteria. However, should someone take a dip in one of these pools and gets water up their nose, some of the amoebas might penetrate the mucous membrane and find their way up the nerves to the brain, where they start eating brain cells.

Evolution Before Your Very Eyes!
Here's a neat site.
It shows the genetic algorithm in action as it evolves a car 'designed' to go faster and further over a terrain of peaks and troughs designed to filter out the weakest, most unstable and least efficient.
You don't need to do anything other than watch, but you can play around with a few settings like the maximum number of wheels - try 4 or 5 - or the mutation rate.
The first generation is just random stuff, often going nowhere with maybe a few making some progress. The trick is, just like in life, that the best are favoured and hybridize so the best wheel size, axle torque, body shape etc are more likely to be in the next generation. Plus a few more random variations thrown in.
Pretty soon a few different models will evolve. They might even hybridize and produce a new supercar; or they may be incompatible and fail, just like in real life.
Anyway, especially if you don't believe in evolution, take a look. Leave it running overnight and wake up to some pretty nifty cars zipping across the landscape. Remember, everything apart from the selection process is random. The only thing that makes it non-random is selection favouring the most successful models, just like in real life.
Careful though; it can be addictive.
Evolution In Progress - The Great Ant Escape
Trap-door ant (Odontomachus brunneus) |
Here is a nice example of two components of evolution: the arms race between predator and prey and co-opting a structure for a new purpose, showing the opportunist nature of evolution by descent with modification. It involves a trap-door ant and how it tries to escape from a predator, in this case an antlion.
First a little about trap-door ants and antlions:
Trap-door ants have massive jaws which they normally hold wide open as they forage around the forest floor until they come up against something which triggers the sensory hairs between the jaws, when the jaws swing forward and clamp onto the prey at an amazing 140 miles an hour - the fastest known movement of an appendage in a living creature.
Antlion lava Credit: Johnathan Number, Wikipedia |
Antlions are the lava of a damselfly-like insect. They prey on small crawling creatures, especially ants but rather than actively hunting they make a pit of sand and hide buried in the bottom of it, waiting for something to fall in. They will even throw grains of sand at the victim to make it fall to the bottom of the pit. This behaviour probably evolved from making burrows and hiding inside to rush out and grab passing prey. A neat solution where the ground is too dry and sandy to make good borrows, so enabling antlions to exploit new areas.
In this video we can see a trap-door ant using a surprising method to escape from an antlion.
This mechanism has been known about for a long time but the question was whether it actually improved the ant's survival rate. To test this, researchers at the University of Illinois, USA, glued the jaws of trap-door ants together and compared their escape success to that of a control group with glue applied but the jaws not glued shut. They found that ants still able to use their jaws had a greatly improved escape rate.
Abstract
Animals use a variety of escape mechanisms to increase the probability of surviving predatory attacks. Antipredator defenses can be elaborate, making their evolutionary origin unclear. Trap-jaw ants are known for their rapid and powerful predatory mandible strikes, and some species have been observed to direct those strikes at the substrate, thereby launching themselves into the air away from a potential threat. This potential escape mechanism has never been examined in a natural context. We studied the use of mandible-powered jumping in Odontomachus brunneus during their interactions with a common ant predator: pit-building antlions. We observed that while trap-jaw ant workers escaped from antlion pits by running in about half of interactions, in 15% of interactions they escaped by mandible-powered jumping. To test whether escape jumps improved individual survival, we experimentally prevented workers from jumping and measured their escape rate. Workers with unrestrained mandibles escaped from antlion pits significantly more frequently than workers with restrained mandibles. Our results indicate that some trap-jaw ant species can use mandible-powered jumps to escape from common predators. These results also provide a charismatic example of evolutionary co-option, where a trait that evolved for one function (predation) has been co-opted for another (defense).
So, not the most important piece of scientific research, coming into the category of "doing silly things to animals to figure out what they're doing", in lead researcher, Fredrick Larabee's own words, but a neat example of how a pair of spring-loaded jaws have been co-opted for use as an escape mechanism in an arms race with a predator. This shows how natural selection works on whatever is to hand and, especially where an arms race between prey and predator involved so the stakes are high, can be a powerful driver of evolution.
Now, project this a long way into the future to some descendants of these ants that have maybe evolved some other mechanism for capturing and killing their prey. We could expect to see these powerful jaws with their spring mechanism retained and fully exapted for an entirely new purpose and apparently having no obvious evolutionary pathway - the sort of structure 'Intelligent Design' creationists point to as examples of 'irreducible complexity' and the subject of another book aimed at people who prefer to believe in simplistic notions like magic performed by an imaginary special friend because only that makes them feel important enough.

Another Gap Closed. No God Found
Blue Beach, N.S. The site is a trove of fossils from about 350 million years ago, when vertebrates first started emerging onto land. Credit: Jason Anderson |
A week or so ago, creationism's god was evicted from a gap which palaeontologists have dubbed Romer's Gap. This is (or rather was) a gap in the fossil record of the early Carboniferous era where there should have been fossils of creatures intermediate between fish and terrestrial tetrapods. Now an analysis of fossil fragments found in just one deposit from that era revealed a rich diversity of intermediate fish-tetrapod fauna sitting there right in Romer's Gap.
Abstract
The lack of fossil tetrapod bearing deposits in the earliest Carboniferous (‘Romer’s Gap’) has provoked some recent discussions regarding the proximal cause, with three explanations being offered: environmental, taphonomic, and collection failure. One of the few, and earliest, windows into this time is the locality of Blue Beach exposed in the Tournaisian deposits at Horton Bluff lying along the Avon River near Hantsport, Nova Scotia, Canada. This locality has long been known but, because the fossils were deposited in high energy settings they are almost always disarticulated, so the fauna has not been described in detail. Recent intensive collection has revealed a diverse assemblage of material, including for the first time associated elements, which permits an evaluation of the faunal constituents at the locality. Although not diagnosable to a fine taxonomic level, sufficient apomorphies are present to identify representatives from numerous clades known from more complete specimens elsewhere. The evidence suggests a diverse fauna was present, including whatcheeriids and embolomeres. A single humerus previously had been attributed to a colosteid, but there is some uncertainty with this identification. Additional elements suggest the presence of taxa otherwise only known from the late Devonian. Depositional biases at the locality favor tetrapod fossils from larger individuals, but indirect evidence from trackways and tantalizing isolated bones evidences the presence of small taxa that remain to be discovered. The fossils from Blue Beach demonstrate that when windows into the fauna of ‘Romer’s Gap’ are found a rich diversity of tetrapods will be shown to be present, contra arguments that suggested this hiatus in the fossil record was due to extrinsic factors such as atmospheric oxygen levels. They also show that the early tetrapod fauna is not easily divisible into Devonian and Carboniferous faunas, suggesting that some tetrapods passed through the end Devonian extinction event unaffected.

Romer's Gap, named after the U.S. paleontologist Al Romer who first wrote about it, was a period of about 15-30 million years following the end of the Devonian era characterised by primitive forests of giant tree ferns and a highly diversified fish fauna, and the appearance of forests with flowering plants, more modern aquatic fauna and a diversified terrestrial fauna. Several hypotheses had been put forward to explain it, including low oxygen levels which couldn't support terrestrial vertebrates, differences in geochemistry which didn't support fossilisation and a mass extinction at the end of the Devonian.

Normally, creationism makes a great deal of these gaps in the fossil record and supposed missing transitional forms, claiming that Darwinian evolutionary theory requires all the intermediates and no gaps in the record, otherwise the entire theory disintegrates. This claim is, of course, nonsense, since the TOE is not a theory about fossils but about how change occurs over time.
Nothing in the theory requires a comprehensive record and it only requires a little thought to realise that, with fossilisation being such an unusual and highly unlikely event for most species, the occurrence of a perfect series for every species is so hugely unlikely it could only be explained by design. In other words, a completely gapless fossil record would not be evidence for undirected, unintelligent natural evolution but for just the opposite. The lack of all these perfect series is actually evidence against creationism and for an entirely natural process.
But still, few creationists give much thought to things like that and like to believe that gaps like Romer's Gap somehow supports them, so it's always fun to watch them ignore it when science closes just such a gap, as it did with this find. It seems to be a difficult concept for creationists to grasp that science is essentially about discovery. If there were no gaps there would be nothing to discover. Significantly, of the myriad gaps closed by science, especially in the last few hundred years, not one single god has ever been found in any. Science only started to make real progress when it began to question whether there really was a god in every gap and went looking.
Chick Embryos Reverted to Dinosaur Features
It's more bad news for the Creationism and the Intelligent Design industry, and this one is going to take a lot of explaining away.
Scientists have shown that inhibiting a couple of genes responsible for facial development in domestic hen embryos, causes the chick to grow a dinosaur face instead of a bird face. The authors also suggest their method could be used to investigate the mechanism of other major transitions in vertebrate history.

Another Of Those 'Non-Existent' Missing Links Found

It must be puzzling and disconcerting for creationists the way a new scientific discovery never seems to support creationism and always seems to support science. Not that this will affect creationist superstition, of course, but there is a very simple explanation for this: science is based on evidence and so is demonstrably true; creationism is a superstition with no supporting evidence and so is not demonstrably true.
It's entirely predictable therefore that evidence will always support science and never supports

Evolution for Brainy People
A friend on Facebook has just drawn my attention to this scientific discovery from last February. I can't think how I missed it with such a catchy title to the paper (Human-specific gene ARHGAP11B promotes basal progenitor amplification and neocortex expansion). Hmm...
It appears then that a single gene might be responsible the the most profound difference between us and the other apes and between us and our immediate hominid ancestors.

Faking It At Lourdes
Continuing my series on the fake miracles used by the Catholic Church to keep the faithful faithful and keep the money flowing in, this one deals with the carefully concocted fraud at Lourdes, France.
This fake is, like the Fatima fake, based on the fantasies of an illiterate peasant girl, Bernadette Soubirous, from a remote village who, as with Lúcia Santos at Fatima, seems to have been trying to impress a couple of friends and who found herself locked into her own childish fantasies by a Church keen to exploit her.
There are three elements to the Lourdes 'miracle':
- The 'visions' of 14 year-old Bernadette Soubirous.
- The 'miracle' cures which come from drinking the spring water and praying at the grotto.
- The 'incorruptibility' of Bernadette Soubirous' dead body.
None of these stand up to close scrutiny.

Faking It At Fatima
With the approaching 98th anniversary of the supposed miracles of Fatima, Portugal, it's worth looking at this particular example of how the Catholic Church operates and how truth becomes an early victim in its incessant search for spectacles to keep the faithful faithful and the money flowing in.
First a bit about 'miracles' in general.
The Catholic Church is notorious for using 'miracles' to convince its believers that it is the one true church, believing in the one true god and that it has a special relationship with the ruler and creator of the Universe. The problem it has to overcome is the problem of having no evidence whatsoever for that claim, so it needs trickery. Experience has shown that 'miracles' are particular effective on the poor, uneducated and unsophisticated people who make up the bulk of Catholic congregations worldwide.
Miracles are especially useful for the Church because, by definition, there can be no physical contradictory evidence, just as there can be no physical evidence for them, because otherwise they wouldn't be supernatural 'miracles' but perfectly natural events with perfectly natural explanations. 'Faith' fills the gap and renders the lack of evidence a mere inconvenience, even, in some strange way, confirmation.

Ignorance & Double-Think - The Bear Necessities of Creationism
Genetically isolated sloth bears rely on habitat corridors to connect populations -- ScienceDaily
This paper is interesting from an ecological point of view, illustrating as it does the importance of maintaining a diverse habitat in order to maintain biodiversity, but it also neatly illustrates something which creationists either genuinely don't understand or about which they feign ignorance.
One of the most annoying questions creationists keep asking, as though they imagine it to be a killer question which destroys the idea of evolution, is, "If humans evolved out of monkeys, why are there still monkeys?" The slightly more educated ones will use 'apes' instead of 'monkeys', but the underlying ignorance is the same. This question can only seem even slightly intelligent to those who have no idea how speciation by population isolation occurs.

A team of Chinese paleontologists has discovered a spectacularly well preserved fossil bird from 130 million years ago which neatly fills the gap in the fossil record between proto-birds such as archaeopteryx and modern birds.
This pushes the earliest known ancestor of modern birds back 5 million years and, because it has several well-developed adaptations, shows the main features characteristic of modern birds must have evolved

The Future for World Religion
The recent Pew Research Center's forecast for the growth of world religion has been greeted by theists in general with something approaching glee because it appears to forecast a decline in the proportion of people with no religious affiliation, which includes Atheists and agnostics, although this glee tends to become muted, especially amongst Christians, when they look below the headlines, because the same figures show the number of Muslims worldwide almost equalling the number of Christians by 2050.
However, it reveals something dark and nasty at the heart of religion and upon which religion depends; something of which no religious person with any sense of human decency can be proud.
And in the developed economies the forecast is far from good news for theism. Throughout much of it, the forecast is that the recent growth in non-affiliation and non-belief will continue to increase both in absolute numbers and in proportion of the population. In fact, the number of non-affiliated is set to increase throughout the world but is forecast to decline in percentage terms because of a larger increase in the number of religious people.

Intelligent Design Arguments Drying Up - Water, Water Everywhere!
Regular readers will remember the dismay that creationists who trot out the 'Goldilocks' argument for intelligent design displayed when it was discovered that yet another body in the solar system may have abundant water.
The problem they have is that they have to convince those to whom they are selling the notion of Intelligent Design that Earth is unique in just about everything that affects life on it - so water on Earth has to be presented as something hugely unlikely, just as Earth's distance from the sun has to be.
Maybe it's just my perception but it seems to me that creationists are not using this argument so frequently

Creationism Is As Dead As The Dodo
Head of a Dodo 1638 - Cornelis Saftleven (1607-1681). Probably the last depiction of a living dodo. Boijmans Museum, Rotterdam, Netherlands. |
For an illustration of the inability of evolution to predict the future and so lead a species to, if not actual extinction, then the brink of it, it would be hard to find a better example than this one from the Indian Ocean island of Mauritius.
Mauritius is famous, for amongst other things, being the home of that enduring icon of extinction, the dodo. The dodo was a flightless pigeon (itself an example of evolution because flight must have been something it lost after having arrived on the island) which went extinct in around 1662 probably through being hunted for food by humans and predated on by pigs. Hunting is probably too strong a word, as dodos reputedly had no fear of humans or any other predators, as there were none on the island prior to the arrival of European sailors. The Mauritius giant tortoise also went extinct for much the same reason.
But this wasn't the only example of dodos being incapable of adapting

Closing The Gap - Why Science Is True And Religions Aren't

The thing about science is that it tends to converge on a single answer, no matter what the starting point. Religions, on the other hand, rarely, if ever converge. If anything, they tend to diverge and splinter into different, mutually hostile factions, each clinging to its 'answer', each unable to muster up arguments why their answer is the right one while all the others have it wrong and each never being able to find that definitive, clinching piece of evidence that would make their arguments indisputable and win over the dissenters.

Pain In The Back For Creationists
Actually, the disc doesn't literally slip; the capsule surrounding it tears and some of the contents herniate out. This causes inflammation and swelling; the muscles spasm to protect the injury and the swelling can put pressure on the sciatic nerves coming out of the spine and going to the legs. This causes referred leg pain or sciatica.

Jim Wells, Protestant fundamentalist and Young Earth Creationist |
The Young Earth Creationist and fundamentalist Christian, Jim Wells, who was appointed Health Minister in the Northern Ireland Power-Sharing Executive only last September (see Loon At The Top), has been forced to resign over remarks made in his campaign to become the DUP member for South Down in the Westminster Parliament. Wells had told a meeting that children brought up in households with same sex partnerships were much more likely to be neglected. The meeting was interrupted by uproar from the audience.
He is later alleged to have repeated his remarks during a conversation with a lesbian couple during door-to-door canvassing. Wells later tried to go into the couple's house to apologise but they refused to let him in or to speak to him. The daughter of one of the women involved, a former staunch DUP supporter, later said her mother would no longer be voting for the party. Although expressing regret that his bigotry had caused offense, whilst not withdrawing the allegation, Wells cited his wife's serious illness as the reason for his resignation, not his politically embarrassing bigotry.

How Wolves Evolved Into Dogs
There is no doubt now that the domestic dog is a domesticated wolf. It has recently been reclassified by taxonomists as a subspecies of wolf, Canis lupus, so instead of Canis familiaris it is now Canis lupus familiaris. It was almost certainly the first animal to be domesticated but ideas have differed over how this came about.
In 1907, Francis Galton proposed that humans had taken wolf puppies back to their camp and raised them, maybe as playthings for the children, but this view is now seen as naive. You can raise a wolf puppy by hand but you don't get a dog; you get a dangerous wild animal. The genes of children who played with growing wolf puppies would probably have been quite quickly eliminated from the human gene pool as well as the puppies' genes being eliminated from the wolf gene pool.
So, clearly something else happened.

Creationists - More Green Than They're Cabbage-Looking
The reason they're so abundant in this part of the world is because they evolved as a plant on lime-rich chalk and soil with high salt content. The covering of soil over these chalk deposits is ideal because that's what they've evolved to live on.
So why doesn't it look like a typical cabbage? Because, from this original wild type, by a process of evolution driven by human selection over thousands of years, humans have produced a whole range of different plants for food, each filling a different function and each exaggerating a particular feature inherent in the wild form. This neatly illustrates how a wide range of morphologies can be obtained by a simple selection process. We did the same with the close relatives of the cabbage, B. rapa, B. nigra, B. napus, B. juncea and B. carinata
The reason we were able to do this is because, at some time in their evolution, B. oleracea, B. rapa and B. nigra hybridized to form three entirely new species, B. napus, B. juncea and B. carinata and this gave a wide range of genetic potential. This is of course, a complete refutation of three creationist assertions; that mutations are always harmful, that new information can't arise, and that evolution can't give rise to new species.

Evolving Together In Amazonia
[Body] Bacteria bonanza found in remote Amazon village : Nature News & Comment
Much to the chagrin of creationists, no doubt, we can trace our evolution by the evolution of the obligate parasites and symbiont organisms that live on and in us - our microbiome. Just as with the evolution of our lice, the evolution of which and their diversification from the lice which live on the other African apes, maps exactly onto our diversification from a common ancestor with those same apes, so our microbiome can show how human groups are related and have diversified over history.
It has long been suspected that the number of different species in our microbiome declined as we became more hygienic and especially since we discovered antibiotics, so a team who studied the microbiome of the recently-contacted Amazonian tribe, the Yanomami, expected to find a high degree of biodiversity - which they did, finding some 60 unique genes. However, what they didn't expect to find was that a number of the Yanomami gut bacteria have already evolved antibiotic resistance, including resistance to man-made antibiotics.
The general view of antibiotic resistance is that this evolves in bacteria in the presence of antibiotics because the environment is favourable to those with mutations which convey resistance in a basic Darwinian evolution by natural selection. However, the Yanomami have no history of antibiotic use, at least not in the way antibiotics are used by modern medicines.
So, there are two ways to look at this - either antibiotic resistance has evolved in the Yanomami's gut bacteria in response to naturally occurring antibiotics or toxins (toxic to the bacteria) which resemble them, or they have been exposed to man-made antibiotics even though they have remained isolated. This latter seems the least likely and the team believe they eliminated it, so, if their bacteria evolved resistance to man-made antibiotics the probability is that our gut bacteria already had the capacity to 'switch on' resistance even before we began synthesising them. And that raises some worrying possibilities for future antibiotics in our continuing arms race with bacteria.

Oldest Stone Tools Show Intelligence Pre-Dates Humans

Black Flamingo Poser for Creationists
These pictures are of the only known all black flamingo. It was photographed in Cyprus in the last few days. There was one previous record of a black flamingo in Israel last year. This one from Cyprus may be a different one, but given that the Israeli one has disappeared and given that Cyprus is an easy flight for a flamingo from Israel, there is a strong possibility that this is the same one, and possibly the only one in the world.
Obviously, the mutation which gives rise to melanism (an overproduction of melanin) is a rare event. We know flamingos produce melanin because they have some black wing feather and some black on their beaks, so what is probably happening here is that the gene(s) controlling when and where the gene for making melanin is switched on (or off) has failed.
The New Forest - No Intelligent Design Here
But when you look at nature and really try to understand and appreciate why things are as they are, the one thing that stands out most markedly is how utterly stupid so much of it is. It is full of examples of pointless and ultimately wasteful arms races as one species seeks to gain an advantage over another in the general competition for resources or even as one species tries to use another as a resource and the other tries to resist it.
The result is the wonderful complexity and diversity we can see and enjoy but to pretend it all has some ultimate purpose directed towards humans is sheer anthropocentric arrogance.
Look at these pictures of thicker broad-leaf woodland and what do you see?
Bearing in mind that it's early Spring here in the UK and most trees are just breaking into leaf, so what you are seeing is the wood without it's canopy. In a matter of weeks this forest floor will be considerably darker than what you see here.

A new study has provided more detail on the discovery reported a year ago that Europeans evolved white skin fairly rapidly about 8000 years ago but not, as one might assume, in Europe itself but rather in three different distinct populations of hunter-gatherers and farmers who moved into Europe, each contributing genes to the 'European' genome.
A paper published in February this year showed that the origin of the Indo-European languages was probably a population of nomadic herders from the Russian steppe north of the Black Sea who appear to have migrated massively into Europe about 4500 years ago. These people are known as the Yamna Culture. Indo-European languages exist now in about 400 different languages and dialects from Irish in the west to Hindi and Urdu in the east.
Ancestral Adam & Eve Probably Never Even Met
Scientists have revised their estimate of when the last common ancestor of men lived, bringing it much closer to the estimate of when the last common ancestor of women lived. The basis for this estimate is the range of diversity in the Y-chromosome and the estimated rate of mutation.
The calculation for women is based on the same principle but based on mitochondrial DNA (mDNA). We inherit our mDNA from our mothers but males inherit their Y-chromosome from their father. Women don't have a Y-chromosome.

Origin of the Adam & Eve Myth
A pair of Old Testament scholars at Holland's Protestant Theological University, Amsterdam & Groningen believe they have found the origins of the Adam & Eve myth in the Hebrew Bible. It is a version of an old Canaanite myth based on the original Canaanite pantheon.
Dr Marjo Korpel and Professor Emeritus J.C. de Moor claim to have found the evidence on Ugaritic clay tablets of a 13th-century BCE story about the gods who lived on the slopes of Mount Ararat, in modern-day Turkey, in the 'vineyard of the great gods', identified with the Garden of Eden.
The top god was El the creator god and amongst the lesser gods in the pantheon or Elohim (children of El) were Adam and his wife. El is, of course, the Hebrew, Christian and Muslim god whom Arabic speakers still call Allah.

Cowardly Catholic Runs Away Again
What I did do, however, was re-issued the challenge to him to hold an impartially moderated debate on neutral territory that panicked him several years ago. The result was the same - total panic, abuse, crude threats and a desperate attempt to save face.
