Unfortunately anything that we don't know about is unidentified, which makes whatever that is a UFO regardless of what it actually is. This is like reading the bible and being a Christian because you believe everything you're reading. There's something strange in the sky, on a video - a video for which we don't know the origin really or if it's been doctored in any way and that somehow leads people to believe in aliens now?
I think that the likelyhood of these flying objects reported or filmed are going to be military aircraft/drone type aircraft.
The chances that these videos are any kind of proof of aliens or alien aircraft are slim to none IMO. I can see how a conspiracy theorist type of mind would run with some of the evidence out there, but for me it's just not enough to feel comfortable saying that I believe.
Interesting stuff though, for real.
