As I said:
"But I will also suggest a practical reason for belief in God: we need theism for other core beliefs like free will and moral responsibility. Philosophical naturalism is probably just going to end up as moral nihilism."
I already mentioned one example:
"As far as I know, you will not find any of the well known atheists defending a strong (libertarian) form of free will that would be required for moral responsibility.
By "moral responsibility", I mean that if an agent has no real power to, for example, avoid murdering someone, then that's destroying moral responsibility. You can still put them in prison as a deterrent, and say they "acted freely" in some sort of sense; but they aren't really going to be responsible for the crime as a moral agent.
Some philosophers may still try to defend a strong form of free will under naturalism.
Naturalism doesn't have to say that physical things are the only type of thing that exist, but it will place emphasis and primacy on the physical world.
So with naturalism, they need to argue that a physical system can develop to the point, where you get an emergent property, that is somehow outside the ordinary physical laws."
Another example, would be that with theism the underlying or greater reality can be moral in nature, and the "natural world" can have a moral purpose.
With philosphical naturalism, the underlying reality is just a blind process and the natural world has no purpose at all.
So while you can say, perhaps, that morality came about for evolutionary "purpose" and is needed for group cohesion necessary for survival, necessary for the passing on of genes; it's not going to connect to the underlying reality in a way that would be seen as meaningful and valuable by typical humans, because at that level everything just becomes a blind process and mechanism without purpose.
