My point is not that religion itself is the motivation for wars, murders and terrorist attacks, but that religion is the principal label, and the most dangerous one, by which a "they" as opposed to a "we" can be identified at all.

The beauty of evolution is that it does provide an explanation of how you can get complexity out of simplicity. It does it by slow, gradual degree. At no point are you postulating the sudden coming into existence of a complicated being.

We have the same genetic code for all living creatures. We have a large number of genes that are manifestly the same, but with detail differences - they look like different drafts of the same book. In extreme cases, like a human and a beetroot, it's like the difference between Matthew and Luke's Gospel - clearly they tell the same story, but with different words. Whereas with a human and a chimp, it's like two different printings of Matthew, with a few typos in one.

What I can't understand is why you invoke improbability and yet you will not admit that you're shooting yourself in the foot by postulating something just as improbable, magicking into existence the word God.

We have to find our own purposes in life, which are not derived directly from our scientific history.

You can never be absolutely certain that anything doesn't exist. But you can show that it's unlikely.

All life evolves by the differential survival of replicating entities.
