Now there is reasoned debate. You label the ideas of a man, who is probably just slightly more knowledgeable than yourself, as silly.
On the subject of biology, Collins certainly knows much, much more than I'm ever likely to know.
On the subject of God, there's a key fact that I'm aware of that Collins is not, so I will assert greater knowledge on that subject than he possesses. That key fact, of course, is that there are no gods.
But look, did you even read the article? You don't see the inherent contradicition in asserting, on one hand, that simply because we don't understand something, that's no proof of God; and then, almost in the next paragraph, asserting that because we don't understand the origin of something (human morality in his case), that's proof of God?
How could it get more contradictory than that? How else to describe that besides "silly"?
