UFO's are real and of all times. I recently heard a story of a native south American tribe that have an encounter with a visitor as part of their history. They say that centuries ago, I don't recall the date, a ship came from the sky and a person exited it, wearing a full body space suit with a windowed helmet. First he just sat at a distance and observe them. After a few hours the villagers were comfortable enough to go near him. Appearently it was a very friendly person. They started to interact with him. For 3 days he hang out with them, laughed a lot, danced with them. He was really good company. After 3 days he all of the sudden spoke their language as if he was born there and talked with them and learned them lots of things. He also explained where he was from. When he left he said he was going to return after a specific number of years had passed and would repeat that after the same amount of years had passed. It was something like 40 or 72 year I believe.
And that is only one tribe. In Africa the Dogon tribe says to have been visited by star people who told them what star, in the Sirius constellation I think it was. And there are many more.
I have never heard of this before. Sound really interesting to research upon.
