Science cannot figure out if God exists or not--true, but does it matter?

"Science cannot figure out if God exists or not."

This is literally true but misses how the progression of our understanding of the natural world has gradually occupied space once occupied by supernatural explanations.

What's left is ethics. Religious people dislike atheists so much in part due to the fear that without a deity's carrot (heaven) and stick (hell), humans wouldn't behave, and chaos would ensue.

Or that, at best, we'd wind up with the tribal morality summarized by the Arab saying "Me against my brother. Me and my brother against my neighbor. Me, and my neighbor against the stranger."

This arena--the biology of good and evil--has been my particular interest for many decades. There's actually a fascinating book about it that I hope Jackie reads someday: The Moral Animal: Why We Are, the Way We Are: The New Science of Evolutionary Psychology.

Sociobiologists aren't saying they've found the Ten Commandments coded in our DNA. Just that we're designed to care for others--at least others who are related to us, others in our gene pool (perceived as our tribe). The great contribution of Christianity was in expanding the notion of "our tribe" to all peoples everywhere.

To put it another way, morality has an amoral basis--the gene pool's need to grow and prosper--with moral results: marriage, good citizenship, the Golden Rule, rule of laws, not men--and the willingness to defend all that, even with deadly force (if all peaceful alternatives have failed).

Religion articulates, shapes, and reifies natural impulses. Science can tell you where those impulses come from. It can't deal with the "supernatural" but it can tell you where the notion that there is a "supernatural" came from.

I have no desire to replace religion with nothing. I want humanity to live by moral codes. But across the rich world in particular, the moral codes of religions are gradually being supplanted by secular moral codes. This has already happened in much of Western Europe, and is expanding in America, though still by a small minority.

The advantage of moral codes based on nature is that nature is the firmest foundation. The disadvantage is that it's harder to explain to the average person. I can say that, living in a very secular neck of the woods--Silicon Valley--I don't see the nonreligious people I know stealing from orphans and cheating on their mates any more than do the religious people I know (and I know many of these as well, via my spouse).

The nonreligious people I know don't picket churches with placards saying "Don't Believe!" They just go about their business, never thinking about religion one way or another. It's simply irrelevant to them.
