Even if they did pick here and now, like you mentioned, the energy and time involved to travel through space even to a very close star are unimaginable.

However, all of those limitations are rooted in our current understanding of physics and engineering, which are not complete and constantly changing. We routinely take for granted things today that would have been impossible a hundred years ago. In fact many of the things we do today probably could have been PROVEN to even be THEORETICALLY impossible not very long ago. So while I agree that what you say is true for our current understanding, I'm not so sure I agree that it will be true in another thousand years (or another million or billion). These technical problems may possibly be overcome by a very advanced extraterrestrial species who has had a few thousand years of experience with advanced physics and engineering. Who knows?

People do see these unexplained things pretty often. I'm hoping that now that every phone in the world seems to have a camera built in, we can get some good pictures of some of these things and maybe have a shot at understanding what they are. When more than one person sees something unlike anything else we experience in normal day-to-day life, it's hard to just discount it, and it makes you wonder. You can't prove they are or aren't ETs, but I do believe people sometimes see amazing things that can't be explained, and I don't think it is all just hallucinations and mass hysteria.

Maybe these flying saucers are being used by gnomes: http://boards.cannabis.com/current-e...e-problem.html
So true, you can't say it is impossible just because we humans haven't figured it out yet, because everyone knows we are just the most intelligent beings right? LOL!
