How do they know that it's an alien UFO?
I'd agree that there the chance of there not being other life is infinitesimal. However, that is a far cry from saying that other life is visiting us. As of yet no evidence has been presented to suggest we have been visited so there is no reason to assume we have been since it's such an unlikely event.
It's a UFO, that means they don't know what it is! If they did it would be an IFO, Identified Flying Object, like a plane or a kite!
If a shaky video of flashing lights isn't proof of aliens, I don't know what is!
Not an alien. Here's an alien...
Not to worry, Isaac Newton used to tie lanterns to kite tails and fly them at night to freak out the neighbors. But, that may not be what this is. More info coming to you on Dec. 21, 2012.

Why can't anyone just admit it was a UFO?...Are peoples minds so limited into believing that we are the only species in the still growing endless Universe.
