Some of your words were censored but agree overall except that Ive seen nothing wrong from what little koran Ive read. The truth of the one spirit comes from such things as one man sitting alone on a mountain top and that one truth has been given to all races. It may be worded differently and actually various peoples were given different roles. It boils down to the sovereignty of the creator. An ohio cheif said something on that to a christian preacher in the 1700's. I happen to know the christian bible but in a real sense. Christians generally dont have a clue and I dont think many followers of religions do. The founders usualy had it, I believe. What you assume the christian bible says is probably taken from them. It is indeed perfect when you trace back to the original and remove biases of the particular translators but its alot different than christians teach and even opposite, overall. Eastern religions amazingly carry most of the same basic concepts. Really I think you have to just see it for yourself first and then you can understand what the various founders of religions were talking about. Ive seen it by selflessly looking out into the universe, for one. The last revelation wasnt like anything I ever considered or heard but it turned out to be true.
For me, the bible, koran, and talmud, are books of laws written by man, and were designed to unite, and control. Islam was started in the 7th century by a spice trader at a time when Christians and Muslims were fighting over spice, and not oil.
I believe the natives and the "great spirit" make the most sense, as does animism. We can live without religion, but we can't live without water, air, sun, and food.
