Do you believe any UFOs are of extraterrestrial origin?

Some but not all are surely extraterrestrial. They may be probes from far off planetary systems of intelligent species now long extinct. Some could still be intelligently controlled craft from some where (out there).

Other explanations for UFOs are top secret military and industrial projects. Others still may be cross dimensional technology used by intelligent beings from other realities that exist along side our own. So the question of are UFOs from other planets... some are others aren't.

It does not seem logical that we are the only intelligent life forms in a vast galaxy such as ours. I believe that E.T. 's may have built the pyramids.

I do think that it is most likely impossible that we are the only intelligent beings in this universe, just doesn't seem possible given how vast it all is, so it wouldn't really surprise me if some of those UFOs in the sky are passersby from other planets, but being a skeptic, I have no real idea. There's really no way to tell unless they do more than observe, if they are.

Maybe its just us from the future guiding time. Couldn't imagine an advanced civilization would have to come here to see us.

I can see most of the world running when there is nothing behind them. Imagination can cause one to see something that is not there. Most people are subject to making up lies rather than they are in telling the truth.

Even in small matters they will add to the subject to make it seem more believable and interesting. Just remember this one rule:Look before you leap,for everything that glitters is not gold.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
