Deep Time

One of the problems Creationist 'scientists' exploit in their target market is a general ignorance about the age of Earth and the lack of any real appreciation of just how much time has elapsed for evolution to occur in. This is exploited in fallacies like claiming there just hasn't been enough time for the present diversity to have evolved and for the complexity in the higher animals that we see today.

To get some idea of just how much time life has been evolving, try this little analogy, which Richard Dawkins quotes in 'Unweaving The Rainbow':
Fling your arms wide in an expansive gesture to span all of evolution from its origins at your left fingertip to today at your right fingertip. All the way across your midline to well past your right shoulder, life consisted of nothing but bacteria. Multi-celled invertebrate life flowers somewhere around your right elbow. The dinosaurs originate in the middle of your right palm, and go extinct around your last finger joint. The whole story of Homo sapiens and our predecessor Homo erectus is contained in the thickness of one nail-clipping.

As for recorded history; as for the Sumerians, the Babylonians, the Jewish patriarchs, the dynasties of the Pharaohs, the legions of Rome, the Christian Fathers, the Laws of the Medes and Persians which never change; as for Troy and the Greeks, Helen and Achilles and Agamemnon dead; as for Napoleon and Hitler, The Beatles and Bill Clinton, they and everyone that knew them are blown away in the dust from one light stroke of a nail file."
[Later note] Incidentally, it's ironic that Creationists use the fallacious 'not enough time' argument against evolution when it's a fatal flaw in their daft myth of Noah's Ark. This myth requires all the diversity we see in every species now to have evolved at a vastly faster rate than that required by the scientific theory of evolution. In some instances it would require a new variant to have arisen more than once in each generation for this diversity to have arisen in some 4-5000 years from just two (or seven) founder individuals.

Once again we see Creationists actually believing the infantile parody they accuse science of believing, seemingly without realising it.

  1. "R" awesome work as usual. Didja see the newset survey from Lifeway Research: Living the biblical life or something like that.

    They survey 1,0000 American protestant pastors about age of the erffs, evolution-n-stuffs. thot ya my like it. good info. Awesomeness.

      Well, obviously, if you wan to know the age of the earth, don't ask a geologist. Ask someone who believes the much-edited, often contradictory, and re-written guesses of Bronze Age pre-wheel goat-herders are the best available reference works on science.

Obscene, threatening or obnoxious messages, preaching, abuse and spam will be removed, as will anything by known Internet trolls and stalkers.

A claim made without evidence can be dismissed without evidence. Remember: your opinion is not an established fact unless corroborated.

Sorry but the spammers are back so I've had to restrict who can post again.
