An idea is about that people in the bible came in contact with aliens instead of angels. Points,

People in that era wouldn't know the difference between some thing divine and something technological.

The Angels used images to convey messages to the witnesses; Aliens use ESP to talk using images in most UFO abduction accounts.

The miracle births in the bible, Jesus, and so on, and Aliens using their test subjects for breeding programs has always been in a lot of cases.

Aliens have been known to give prophesies, and here’s a line...Ezekiel 1-28, speaks of a wheel that flies too.
"And I looked, and, behold, a whirlwind came from the north, a great cloud, and a fire infolding its self, and brightness was about it...." Then it goes on to describe four creatures with four faces, one man, one lion, on eagle, on ox.
Lion, has always been a main symbol for the UK, and eagle the US of course, it’s a stretch but hey, so is faith=P thought?
