Note- I'm not very religous My theory on everything is that during the aztec and mayan time ( also egyptian...) Aliens came and visited us and mated with us. How else could we have evolved so fast? How else could we have made the pyramids? I think Jesus might have been one of these "advanced beings" and was just using technology or just his brain when he was healing us mere humans. People saw this , wrote a book, presto religion is born. Yes I believe there is other lifeforms in the 630 sextillion planets out there. Or maybe im crazy, I don't know....
