Depends on if the universe is truly vast and ancient
If yes, and if life can pop up elsewhere (very plausible) then the odds of a superintelligence already existing before us are extremely high (if superintelligence is possible) since we're trying to make it ourselves.
God, well, God if it exists is way more based than ancient religions and their bad interpretations
Also, I've seen evidence of God personally through experience, as have other people. Interestingly, Abraxas might exist. If not, this could have been "the real God" using Abraxas as cover. If not, it could have been a superintelligence, or intelligence agencies (human tech) .
