Were Humans Domesticated?

No new species of animal has been domesticated on Earth for 4000 years.

Why is this?

Do humans not have the ability to domesticate animals?

Is it coincidence that stories from around the World of aliens visits, also date back to around or before that time?

Did aliens, on a visit to Earth, domesticate the animals? If so, did they also domesticate us?

If they did, then did they instill, in us, our character?

The Sumerians claim that the “Anunnaki” visited us in search of Gold and gave us the abilities to mine it for them.

The Hopi Indians also claim that aliens visited us in search of Gold.

Did these aliens instill, in us, the concept of religion?

Did they think that they could leave us and on their return, we would worship them as Gods and present them with Gold in our adoration?

If this were the case, did they underestimate our abilities to think and reason? Expanding on the religious concepts and finding more and different beliefs.

This, of course, is speculation but why is it in 4000 years, humans have not seen the need or lacked the ability, to domesticate more species?
