What can God be proven to have done in the universe?

When I look into the sky at night, I see what I believe to be an intelligent universe. That just maybe, never had a beginning but has always been. Other than that, I think gods are invented by humans that are scared of death or can't imagine never existing again after death. Bibles are written in order to control and frighten the masses into doing as they are told, or they will go to a fiery hell. But maybe just maybe, we do have a soul, and we are all universal travelers. That after death we remember every part of the universe we have visited and every life we have lived, that would be cool. Who knows for certain. But if it is the god of The Holy Bible, he is a very cruel god, and I don't want any part of him. We have no proof of anything.
