To the people that believe them, all religions are equally valid RAZD. All people are essentially equal in their ability to have spiritual experiences. The bible even speaks of many other gods that are worshipped by other cultures. to those other cultures, their gods and their spiritual experiences with them are quite valid.

Yes Buddha was a real guy, just like Jesus was a real guy.

As I mentioned above there are notes about Jesus and his followers in Roman history. The jews also have notes in their history about him. The NT is a collection of writings from his first followers.

There's actually quite a bit of stuff.

Yes, you can quote me on that btw. Quantum mechanics works with dimensions and energy and matter. It's proved all sorts of stuff that people wouldn't otherwise believe could be possible. elementary school children are starting to experiment with it on a simple level. I don't remember where I read it but it was recently, about some school kids and two bowls of rice... I will try to remember and find that for you. essentially, they turned the rice into wine (started anyway) by telling it they loved it everyday. the other bowl of rice, they told it they hated it everyday and it rotted. took them 30 days or so to get it going. Jesus turned water into wine in a few minutes.

Energy affects matter RAZD. God is spirit. God is love.
