So I know a lot of people are gonna write this off as fiction right off in the beginning because aliens don't exist or whatever. Humor me. The theory has surfaced a few times and I want to know what the fg community thinks. The theory goes: Long ago, during the first blemishes of life (i.e. Mayans, Incas, etc.) Alien(s) came down and taught humans to do, well, everything. Building temples, irrigation, sewer systems, all that stuff that makes life practical. In return, humans worshipped them as gods. Opinions?
