Just for fun let’s consider the evolution of atheists as a species.
You make an interesting argument. You may be absolutely correct that, over a long period of time, whatever it is cognitively that promotes atheism might in fact evolve out of our brains. In fact, there’s as yet insufficient evidence that human intelligence itself has any long-term evolutionary survival value.
On the other hand, human society and human belief has been changing many orders of magnitude faster than biological, genetic evolution can account for.
In evolutionary terms, we’re in a period right now of very little selective pressure, both biologically and socially. Almost any genetic variant of human can survive today (because of vastly improved medical science) and because of Western liberalism, almost any social ideology can get a foothold in some sub-population.
This can’t go on forever. There will soon be some sort of bottleneck, and some societies will be selected for and some against.
It’s not just a matter of more babies, either; if it were, in biological evolution, there would be nothing but insects. And even socially and ideologically, if it’s just a matter of having more babies, the Muslims have quite the edge on the Christians. But again, I don’t think that just numbers of babies is the determining factor.
The one trait that has caused more disproportionate economic success in human civilization is natural science. And atheists have the advantage of being more-or-less thoroughly dedicated to this trait. Almost all theistic religions, on the other hand, at some point balk at the use of some science. So even though atheist numbers might be low, we might better preserve this important trait. Evolution is full of examples where the preservation of some trait is more important than just raw numbers of offspring.
Furthermore, there are a number of religious believers (mostly non-Catholic, AFAIK) who seem to be
aching for the Rapture and subsequent Armageddon. If such people get their hands on the United States’ or Russia’s nuclear arsenal, bye bye planet Earth.
With all good luck, we will colonize space soon. If we do, there’s going to be very strong selective pressure in that environment for careful, realistic thinking 24/7. Even if religion makes it into space, I suspect it will become very different.
Well, are atheists an endangered species?
If this is true is it an argument for, or against, intelligent design?
I don’t think that even selective pressure against atheism would be evidence for intelligent design. An intelligent designer desiring theistic belief would simply implement such belief at a more basic level. It would just be evidence that a certain mode of thinking had survival value, and (in my opinion) would argue against the theory that thinking has survival value in proportion to its realism.
Only time will tell. Biological evolution works on timescales of tens to hundreds of thousands of years, and even social evolution works on scales of multiple generations. You and I (at least in our present bodily forms) won’t be around to see the results.
