Why Are We So Sure of Our Atheism?

I rank high, percentile and openness. I'm open to tarot or Ouija boards in the sense that there's an actual spirit moving them. We're using these great books as mirrors.

That's not how we evolved. Survival and reproduction doesn't actually require a higher level of consciousness. This is a Jungian quote again. Why do we think we are so sure when we're very definitive at the ideas of God? Because quantum mechanics has basically already proven the existence of God
