Atheism

[RoadRunner79]

In context, I can a be reasonably certain. Additionally, confidence in your experiences are not in a vacuum -- every individual has a slightly different cumulative case undergirding their beliefs.

Context actually often tells us how divine experiences aren't actually divine at all. For example, it's interesting how people's religious experiences reflect the religious culture that they are already immersed in. My 'religious experience' where I heard a demonic voice behind my head just as I was getting to sleep mirrored the role playing experience I had that same evening.

Point is, people are using the same brain to determine what is a response to a sensory input, a religious experience or a momentary imbalance of function. The brain is very active and dynamical system with different parts very finely balanced. You cannot trust the same brain to tell the difference. This is why we require impartial observers.

I would agree, that you need corroborating evidence.  Either from other people, or other sources of evidence.
