I think of it like a flat place to work, all major world religions hold the tenants required to build a functional society in the long term; leaving those building blocks up to the short sighted whims of man has ended in disaster, dare I say, every time its been tried. The soviets thought that logic and reason could solve for all prices in the economy, their people starved; the Nazis thought logic and reason could solve for the morality of their population, and they murdered millions.

I'm wouldn't say I'm religious, but I have serious reservations about the idea of man about putting their faith in themselves rather than a higher power; there seems to be no reasonable stopping point to that, so then, at the logical conclusion you see any behavior justified under the guise of fixing a cultural issue (genocide), furthering mans knowledge (forced medical experimentation), fixing the economy (inflation), etc.
