Study Puts Hole In Comet Theory Of Life's Origin

Astervitude writes "A new study by US and Japanese scientists has put a serious dent into one version of the popular panspermia theory that credits comets for bringing the seeds of life to Earth. Surveys conducted by the University of Arizona, the National Astronomical Observatory of Japan and others now show that objects from the main asteroid belt between Jupiter and Mars were largely responsible for the period of Late Heavy Bombardment that ended 3.9 billion years ago. UA Professor Emeritus Robert Strom believes that no more than 10 percent of the Earth's water comes from comets and any oceans then extant would have been 'vaporized by the asteroid impacts during the cataclysm.'" Interesting, because this directly contradicts the Nova mini-series Origins that just finished running on PBS. Science never stops moving.

    Yeah,

    why would man and animals need eyes if they couldn't see before, sight is a very high-level ability, a creature without sight doesn't realise he needs it? Also in 'natural selection' humans would have been eaten by everything without sight no matter how developed the brain was.

    If we came from the ocean then why can't we breath underwater and if we are the most 'evolved' of creatures then why are the birds flying around the earth like it's going out of fashion? We're wingless, can't go underwater without breathing equipment, the ascent of man? Yeah right.

    I'm sure if these 'scientists' really thought about it, evolution is absured, mutation is more accurate, but I wasn't a piece of garbage from 10000 billion years ago. I mean even micro-biology points to an intended design. How come nobody talks about entropy no more? Oh if we we're the offspring of monkeys then why arn't monkeys turning into humans?

    I think Genesis 1:1 covers it.
