Why mainstream science is not talking about Atlantis and Lemuria?

Atlantis was where Mauritania now sits

It just ruins the narrative and makes the paid intellectuals looks stupid. lol

They have to respond accordingly to keep their lifestyles intact.

No clue,they are always ignoring and covering up history too. I think maybe we came to earth and killed the inhabitants here and we dont want us to know. Something is weird, that is for sure

They want to hide certain demographic true origins

Nestled in the mountains between France and Spain, there is a semi-isolated population of native European people that have long puzzled anthropologists, linguists, and historians, because although they are Caucasoid, they do not fit in with the rest of the European populations.

Because the nonhumans are currently in control of Earth are the invaders that destroyed Atlantis and Lemuria.

If you learned the truth about them, you might figure out you have been enslaved by alien conquerors.

And what do you propose these invaders look like? Are they genetically related? Are they in another dimension or frequency? Are they reptilian? Most common answer seems to be that they blend right in with humanity and can come and go as they please.
