aliens and religon

I have also wondered if the "Garden Of Eden" was actually on another planet...

What if they're possibly our biblical Angels
sent at times by God to intervene or aid us in our triumph of ignorance
I've seen footage of a UFO @ the scene of 9/11 right before the planes crashed into it.. it darted from the side of the building 2-3 miles away until it was a speck and then flew directly at the helicopter at enormous speeds and came inches, INCHES away from the helicopter and darted upwards and away leaving a very small trail of white "steamy" looking exhaust.
or possibly the government used technologies obtained through unknown means to create a vessle that could possibly do such a thing... and the explaination for them being there, is to make sure their plans follow through or to survey the scene for the impacts... either way its just seemed odd..

if i remember correctly, that video was proven to be a hoax

Can you point my in the direction of some facts that its a fake..
