THEY are a false "god" who never wanted "good" things for humanity, just messed up and used them for millennia, yet they aren't the source of existence in this universe.

Gods have nothing to do with the "beginning" of existence, but the false "god" everyone refers to is the cause of half of human ignorance, the other half was actually humanity own choices.
