Atheists of SW: How certain are you that no higher power exists?

I'm open to the possibility of a higher power, it's just defining that higher power which is the tricky part. The alternatives are not limited to just monotheism or polytheism, but also things like deism, pantheism, or dualism. There's so much we just don't know about the formation of life or the origins of the universe

But if my options are between no god at all or the Abrahamic god of the Bible, which is usually how the argument is framed, I'm far, far more inclined to be certain of the former. The God of Christianity is logically inconsistent on so many dimensions that believing in him raises more questions than it answers. It would make more sense for there to be no higher power than to be subject to that specific deity.
