I assume you believe the world will be better off without religion - In what, then, do you believe, if not God?
That's a very loaded asserion/ question. I'm not going to bite, much.
Gods and religions are inevitable inventions , in the absence of something else to provide the same psychological comfort. When they cripple someone's thinking, they're bad. At least-bad you end up with a load of Vintys, going about the place with one mental hand tied to a foot because that's what their psyche tells them they have to do, while they lecture others on how to walk. OK I'm mixing metaphors.
"Believing in" something invokes a chosen fantasy. Those often provide a mental framework on which to hang one's version of reality. I don't do "believing in". "God" is just one of a number of those structures people use. It's a bit like a football supporter demanding to know if you support United or City. If the answer is neither, - shock and awe - it must be a different team so which one?
I don't have a need of a football team to support, or an imaginary friend who somehow did all the stuff which is hard to even partly work out.
Human behaviour is entirely consistent with increasingly well described - and better evidenced - mechanisms at the heart of studies on the evolution of consciousness. Darwin was one to write about it, it's still being discovered, mechanisms worked out. Just as the evolution of the organism does not necessitate or suggest some exogenous creator, neither does that of consciousness.
Football teams and religions (or gods) are neither a necessary nor sufficient part of existence as we see and understand it.
Nobody has all the answers. Physicists can no more tell you what came before or beyond the Big Bang than the religious can tell you who made their invented god.
