According to Zecharia Sitchen, a Sumerian scholar who deciphered ancient Sumerican texts, it was the ancient non-human aliens who came to earth many thousands of years ago to mine gold. Why gold? This precious mental they found on earth was effective in cleaning up the polluted environment in their home planet in the galaxy.
First they used their own crew to dig gold but they complained and rebelled, so it was decided to create a slave race to do the dirty work. Thus humans were created to dig gold in the mines. This slave race was given a level of intelligence; smart enough just to follow orders but otherwise dumbed down.
