I don't think I have every had a thought that has not already been thought of and nothing is new under the sun for a long, long time. We just share what has been handed down to us in the form of books, etc. and if our minds are open enough, we have the world at our finger tips!
As far as being saved, this did not exsist until the dark ages. You have always been and always be and to think otherwise is to be someones slave. Not one is greater than the other, your body may be better or worse, but your spirit is as powerful and strong and eternal as any other.
