Where did religions come from?

All of these that are religions, stemmed from two things...
Some fundamental questions about the natural world around our ancestors... The sun, the moon, the stars, the planets, the weather, ect... combined with the eventual worship of psychoactive plants and fungi due to such a deep appreciation for the experiences that came from eating different foods of the Gods.
Some scientists and historians think that psychoactive plants and fungi helped shape the very idea of there being something else out there... a spirit world.  Something greater then the everyday "normal world" that our ancestors experienced.  Some scientist even believe that this gift could very well have kickstarted the self awareness we have, that eventually led to reason. Which is known as that which separates us from the other animals.
Then, the ideas of a spiritual realm gave way to actual shamans who specialized in guiding people on these spiritual trips that they'd go on, which then evolved into stories of Gods, and other worldly realms, and eventually because of politics... One God. 
1. In the macro cosom... It was, "I wonder what all those points of light and that big glowing ball is at night...  And what that big glowing ball of fire that moves across the sky  is in the day?" And the stories that insued from that understandable wonder... Mixed with...
2. In the micro cosom..."WHAT IS THIS BLESSED THING FROM ABOVE... That is making that bush burn and talk to me while allowing me to see the very fabric that makes up reality?  All I did was eat this little red and white mushroom, or brown mushroom, or cactus, ect.
That is not in jest either... there's tons of real historical evidence and hundreds of paintings ect. to back it up.
That the Suns movement in the day and the moon and stars movement in the night skys and other natural phenomenon, mixed with the worship of psychoactive plants and fungi are the basis for all of the world religions... And that the deities themselves... Horus... Osiris... Kristna. .. Jesus... are representations of the "king of kings" or star of stars... our home star... THE SUN!  And that the 12 constalaions, or zodiac signs, are always the 12 tribes of israel, or the 12 apostles, or the 12 this or the 12 that...
  Isn't that cool!  I think it is.  It makes the whole idea of religion and spirituality more tangible, beautiful and even more acceptable to me then anything else could, because it makes sense to me...
