Relying only on experience for perception seems limiting and a bit black and white to me I guess. You might experience one thing in a certain way, and later change your perception, then upon looking back at that experience percieve it in a new way. Perception is more than just experience.

I grew up extremly christian, I am an atheist.

I fully understand that peoples perceptions of the world differ, I understand science, I understand the middle world which we walk in. I don't have a hard time accepting it.
