It is quite true that many scientists, many physicists, maintain that the physical constants, the half dozen or so numbers that physicists have to simply assume in order to derive the rest of their understanding ... have to be assumed. You can't provide a rationale for why those numbers are there. Physicists have calculated that if any of these numbers was a little bit different, the universe as we know it wouldn't exist.

A god who is capable of sending intelligible signals to millions of people simultaneously, and of receiving messages from all of them simultaneously, cannot be, whatever else he might be, simple. Such Bandwidth!

The rule of thumb based into the brain by natural selection would not have been, Be nice to your kin and be nice to potential reciprocators. It would have been, Be nice to everybody, because everybody would have been included.

What is the purpose of the universe?" is a silly question.

In true natural selection, if a body has what it takes to survive, its genes automatically survive because they are inside it. So the genes that survive tend to be, automatically, those genes that confer on bodies the qualities that assist them to survive.

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

All animals are minor variations on a very particular theme.
