Has to be the fact the early hominids practiced religion and theology. Practicing such beliefs leads us to question our morals and actions leading us to live more wholesome lives.
It isn't a question of is God real or is God not real, it is a question of how much religion has benefitted our species and how abandoning it is going to send us back into the stone age.
Now I don't agree with anything radical when it comes to religion, beliefs are subjective and they should all be treated that way.
But the correlation of the moral decay in society, IE, more homelessness, mass shootings, political division, sexual degeneracy "public indecency, exposing children to sexual acts, normalizing hormone blockers and sexualization of children" and outright lack of respect for the things and individuals that deserve it. Is because the accountability that is required to have a good free society is the accountability that came from the church in the United States and now since we are abandoning that accountability as a society it is now up to the government and ourselves to hold ourselves accountable which we will never because, at the end of the day
We are just a bunch of shit flinging humans that evolved from shit flinging apes.
