Were humans made to mine gold?

I heard this theory somewhere (i think on JRE) and he said that humans were made to mine gold. That some ancient alien came to Earth and created us to mine gold

You lost me here.

Actually, the *rarity* of gold is fabricated by humans. Same with diamonds. Some companies in india/africa control how many gold/diamonds get released each year, not an alien.

Ehh..if this is the same story I heard, then they say the aliens left us because they were losing control of us.
I don't believe it but anythings possible I guess.
