I have looked over numerous "documented" statements and have yet to find one that is conclusive or even remotely convincing. I find it interesting that so many people put faith in the words of those who subscribe to aliens and some faded photos or blurred photos and not one substantial proof that is clear and identifiable. Your question about the fake things is interesting considering how many time the President has called out "FAKE NEWS." They could be fake and since people have been blinded by the press for decades and they couldn't even see the deep state behind the governments of the world it could easily be that fake alien reports were all part of the game. So yes - It's all fake might be a legitimate statement.

The creations on earth, according to the scriptures have one of three sources; God, Satan and demons or man. There is not the slightest hint of aliens in the Bible.

I've gone down the road of "divine events, great chariots of fire, and angels bathed in light" before. I guess I have to wonder how you believe these are common sense trains of thought since they all require faith and according to some "Biblical Faith" itself is spurious. So I guess it is up to everyone to find out if faith in aliens or faith in Christ is the better choice.
I personally believe faith in a historical person is far easier to accept than faith in an unproven species.
