strange story.

Or perhaps these crashes are intentional by the aliens to distract us from their real actions
nah, i believe most of these UFO-myths are fake. But i do however believe that there's other life forms in the universe. But that some of them has visited earth? nah.
Let me put it this way:
there are approximately 7*10²² stars in the universe, aka 70 000 000 000 000 000 000 000 to spell it out. If we assume that each one of them has three planets, and where only one on 1 000 000 has ability to support life. and between these, only one on 1 000 000 000 has intelligent life, and between those, only one on 1 000 000 has extraterrestrial travel devices, there are a total of 210 of these civilizations. If they are spread evenly in the universe, it would take approximately... ah, i don't bother counting. But the closest star to our sun is approximately 4,2 light years away, or 39.9*10¹² kilometers.
But i'm not saying it's impossible, just that i think it's highly unlikely.
