It could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology- and designed a form of life that they seeded onto perhaps this planet. And I suppose it's possible that you might find evidence for that if you look at the details of biochemistry, molecular biology, you might find a signature of some sort of designer.

You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution.

I don't want to sound callous. I mean, even if I have nothing to offer, that doesn't matter, because that still doesn't mean that what anybody else has to offer therefore has to be true.

I can't be sure God does not exist... On a scale of seven, where one means I know he exists, and seven I know he doesn't, I call myself a six... That doesn't mean I'm absolutely confident, that I absolutely know, because I don't.
