Is there evidence that the gods worshipped by ancient civilizations were actually spacefaring extraterrestrial beings?

None.

Nothing.

Nada.

Nonsense.

There's zero proof that any sort of Greys or Reptilians or whatever have ever visited Earth or are even capable of Space Travel. Such nonsense about Ancient Aliens are the result of hippies from Firang countries smoking too much weed and snorting far too much cocaine.

As it is, such theories are basically just another form of Firang racial prejudice, suggestions that the achievements of other non Firang Civilizations weren't achieved by the talents of those peoples themselves but by the dubious gifts of mythical aliens.

Those who believe such nonsense should free themselves from delusions by worshipping Ma Chandi.
