Landy I think you are right. I wonder how more rational christians would handle it. Evolution has been accepted by millions of christians but very few Muslims. Would the realisation that life can arise spontaneously from geochemistry be any more of a challenge?
I honestly believe it would make little or no difference. People who believe in a god do it based on a faith. They have to as there's no evidence available to support their beliefs. As their faith mechanism has no basis in rationality to start with they would simply shrug their shoulders and carry on believing what they've always believed. The opium of the people does a great job of dulling the senses.
Yes there will be exceptions and some would question their faith, but it wouldn't be on grand scale.
