Little Hawk,

You don't have any scientific evidence of AFOs. You may have hearsay and testimony, but you do not have any reproducible experiments or observations.

Even if there was a ship with little green men parked on your lawn firing "shut up barking" beams at your wiener dog and they told you that they were from alpha century, you would still not have scientific evidence that they actually were aliens. All you would have is their word for it. For all you know they could be some very eccentric folks who grew up next to a superfund site in New Jersey.
