Are the demons and angels ancient alien enemies?

Is there any connection between sorcery and alienology? I read many books about the angelic or demonic entities were ancient aliens and the wars between them were real and not spiritual.
LIke the famous flaming chariots of the greek gods.All clues are pointing to Ufos.
I’m very curious about this topic and also i want to ask you if you have encountered any kind of alien lifeform during soul travels…
