I tend to lean towards humans being the product of an alien breeding program 200k years ago. 

The unanswerable question in my mind is why? If it was to mine gold then what is the greater use of gold? Is monoatomic gold that valuable/useful? Has Bitcoin been deployed to get us to move away from the metal? 

These are the kinds of rabbit holes I don't find particularly useful in pursuing. 😆

I'm always happy to be enlightened though.
