Kevin, simple solution. You work on an Airforce base that has 3-4 F-16's taking off all throughout the day (I know because the damn things wake me up every freakin morning before class). Just walk over to them one day before they take off and have them do a fly by over your house and if the thing appears they will demolish it!
seriously though, I'm kinda up in the air about it. I like many other people that have replied believe that there is others out there somewhere, but just not sure if they have visited us or not.
The only way that I'd be convinced is if one came up to me and asked for a race
