There are no absolutes ... but because I don't believe in absolutes, I can't be absolutely sure of that!

"you just resort to the pious sounding get out, of science not being sure of everything."

It may sound 'pious' to you, pete, but it's an inescapable fact.

By the way, pete, if you attack evolutionary biology - which is based on the accumulation of evidence and hypothesis testing - you attack the whole edifice of modern science. You not only attack Darwin and Dawkins but also Newton, Einstein, Hawking etc. The fact is that by steadily revealing the true nature of reality, modern science threatens the whole edifice of religion - and has done for several centuries now. That is, of course, why the Inquisition put Galileo under house arrest.
