Hey this is a neat little theory that is pretty harmless and believable
UFOs and Aliens are Time Travelers Arriving to Confirm Historical Facts
I always wonder about that UFO story about how jimmy carter reported a UFO, and then when he became president he tried to do something about UFOs or something, and he had a meeting with the CIA, and then was seen crying alone after it to himself.
I wish someone would friggen ask him about this over and over again until he answers since we're still blessed to have him.
Anyway, it'd make sense to me, that a god loving man like him, could find out from the CIA that the aliens were ourselves from the future, long after determining that religion is not real, and they are here just confirming historical facts.
That'd make him cry, and keep it to himself to the end I reckon.
