I think you're confused. The truth you're talking about exists outside of both of those contexts (theism VS atheism).

Religion is just a collection of beliefs that may or may not involve "an invisible man in the sky". Theism VS atheism are mostly orthogonal to the point you're trying to make.

People are driven and indeed may have a need for a sense of a higher power.

Having a shared sense of purpose is very powerful for people.

You don't get that from an atheistic Church which is basically just a club where the only shared purpose is disliking something.
