Myst,
That thought is never new is not correct. If so, then we would never have developed. Our technology would never change. We are human becuase we are able to think original thoughts. Where do computers, cars, trains, boats come from, original ideas.
Your theory contridicts itself because new religions would never be developed if it were not for new ideas. Just look at Greek Mythology. Where did these God's come from. Original thought.
By the way. We are all individuals, not by thought but by genetic coding. Even twins at the genetic level are different.
"No matter how many times you save the world, it always manages to get back in jeopardy again! I feel like the maid; "I just cleaned up this place! Can't you keep it clean for ten minutes!"
