I tend to agree with the sceptics in these kind of discussions. Our brains are very complex, and we as drug users should know that experience != truth.
However, I always have an open mind. I find this simple fact VERY interesting:
Stuff exists.
Which means something. Stuff (the universe, we, etc) should not exist... should it? Why is there stuff?
Whatever reason - that is my god. I feel no need to know more, as it's impossible.
I would like to explain to the OP my theory about why he knew what he did, but my english is not good enough. But read about conciousness, and you'll see the brain is doing most of it's thinking and learning without we even knowing (councious). Which means we pick up a lot of facts that we don't know we know.
