Nice video!
Yes, iv studied these phenomena, and in every ancient story from around the world is some kind of super being, who gave the population knowledge to start a civilization. And in some parts they left evidence about that, like the Sumerian stories or in the Vedas, or the Mayas, Egyptians and many more cultures have a story.
And the truth is, something is still here.

Im a researcher in UFOs ,and im connected with investigators from all around the world, and i can say this, the phenomena is real, but nobody knows who or what they are.
