Dr. Neil deGrasse Tyson on UFOs

This is long at 11 minutes, but totally entertaining and just a great example of why he’s such a great science speaker. It’s a spontaneous response to a question from the audience and he goes off on the fallacy of Argument from Ignorance, the problems of eye witness testimony, lack of evidence, and finally a complete disdain for any alien culture that crash lands in Roswell.

Don’t tell me you came across the galaxy and you can’t land on earth. Go home, bring me someone who can.
