So why are these University of Colorado at Boulder people – and New Scientist – determined to prove that God must have created life?
Look, I don’t care, but consider this:
Just when claims for Akilia, as evidence of life at 3.82 billion years ago have not held up, some researchers are even more ambitious than that.
As reported in New Scientist, Oleg Abramov and Steve Mojzsis of the University of Colorado in Boulder suggest that life could have existed on earth as early as 4.4 billion years ago:
… hardy life-forms could have survived if they were buried underground.
They were using a computer model and they assumed that these primeval life forms were extremophiles (simple, extremely hardy life forms).
… heat from the impacts would not have penetrated very deeply into the underlying solid crust. The layer heated to the sterilisation point, about 110 ̊C, would be only about 300 metres thick. High-temperature ‘extremophile’ microbes, like those in the hot springs of Yellowstone National Park, would have survived at greater depths, down to their limit of about 4 km.
Mojzsis argues that the Late Heavy Bombardment of Earth by asteroids “pruned, rather than frustrated, life.”
That conclusion is reasonable, says Kevin Zahnle of NASA’s Ames Research Center in California.
It certainly is, if you are looking for an argument that God created the first life on Earth. I wonder if either he or New Scientist have thought this one out ….
In fairness, I must warn you that I consider New Scientist the National Enquirer of popular science magazines, and I am also wary of computer models in these situations. So I would just wait and see.
