I read somewhere (and need to find that source and post it here) that it has been theorized that Leonardo DaVinci was an alien and that is why he was so far advanced than anyone else of his time with regards to all of his inventions, most of which couldn't even be made because we didn't have the technology to do so (i.e. airplane, helicopter, etc....).

Also, why he understood the true relationship between Jesus and Mary Magdeleine and the fact they were married and that Jesus was actually just a mortal profit used to create Christianity, especially Catholicism. And, why he understood that Mary was in fact the Holy Grail. Also why he was a leader of the Priory of Sion (in fact, many believe all the members of the Priory are/were aliens).

As I look for my documentation to post here, has anyone else heard of any such theories??
