My question is, why don't we fly up to these figures and get close enough to see them in more than just a blur?


Why don't we get so close we can see through their windows, if they have any.. or let them see us.

The plane was being chased by a ufo, why didn't the plane let the UFO catch up?


The way they move together, kinda makes you wish we, as humans, lived in a world where we were able to get along and communicate so efficiently, no more wars, no racism, no theft, no poverty.

If we are being observed, i hope they understand our language, i wish i knew theirs, i would say 'save us, from ourselves'

what does everyone think? what would you say? is it a hoax? do you believe it? why do you think they are watching mexico?
