One of the problem with these types of discussions, is that often the subject gets side-tracked to questioning the existence of God. Even if it could be demonstrated in a lab that life could arise by the oft-mentioned random alignment of molecules to form amino acids and proteins (okay, i'm not a scientist, and i'm probably mangling the terminology, but i think you know what i mean), that would be neither a proof that God did not exist, nor that life did not arise by Creation. By the rules of logic, you cannot prove a negative. You could, however, assert with a completely sound logical basis, that you believe that God exists, but that life arose spontaneously, not by Creation. The best that science can ever hope to assert would be that life can arise by random chance, not that it necessarily occured that way. Of course, those who hold Creationist beliefs are in a similar situation - there is no way of being able to prove that life did not arise spontaneously, without divine intervention. Interesting arguments in support both sides though, and i have enjoyed reading the thread 🙂
