I can now say that I have. I thought it was a meteor (though even at 12 y-o I still thought it looked odd for a meteor) until I watched the Disclosure Project and got interested in looking at pictures -- then saw a picture of the exact same object over Giza.I'm not saying it was alien. I'm just saying I used to think I knew what it was, and now I don't know. That IS the only definition of UFO.Finally: Q: How do you deal with someone who doesn't believe in UFOs?A: Chuck a pencil at the back of his head and wait for him to yell, "OUCH! What WAS that?"
