If there is a rational reason that aliens somewhere in the galaxy will make contact with us, there is none. We are a tiny spinning rock in a solar system more than 4 light years away from any other solar system. If our own solar system has life forms out side of earth, they are either very primitive or bacteria type substances. But if there truly is another form of intelligent life somewhere in our own galaxy and somehow are close enough to us that we can detect them in these videos I have no idea why they would be hiding in the shadows and offering brief glimpses with almost little to no evidence of them, or why they would come this far to play hide and seek if they are already here. I think that the real solution to all these ideas is that if you want to see something, you will try and see it. Thats how the mind works, and these people that want to see UFOs will find irrational evidence to support their want. Thats it. Theres nothing else, and no logical explanation to why aliens would come at least 4 light years to hover around us for thousands of years and not do anything
