I personally think that saying definitely that there is no higher power is just as arrogant as the religions that say that there definitively is one. My personal belief is that nobody has supplied me with sufficient enough evidence that God exists so I do not believe in one. At the same time there isn't definitive evidence of some type of superior being. When I say that I don't mean God. God is bullshit and was created to manipulate people through religion. I mean like something/someone/some civilization that has advanced enough to create matter, terraform, put us into a simulation and make us feel like we have free will. That is more appealing than some "all knowing" guy in the sky that let's everything happen because "he knows best and we just have to have faith." No thanks.
