Reptilian
???

Absoutly none.

they come in "piece"? how about peace, duh,,,

Thank you for being nice and pointing out my mistake. It's refreshing to meet friendly people like you.

Have you ever met one? Cause I haven't, which means only one thing...None of them exist, in all possibility.

Did you know the U.S. and Russia were in a race to seize technology remarkably similar to reported UFO sightings during WWII? Or that before it was unveiled publicly the SR-71/F-117A/F-22/B-2/B-1/etc. were flying all over the United States (Mainly Southern Nevada, Utah, and Northern Arizona, New Mexico areas)?

I'm yet to see an alien, but I have seen a number of UFO's...Which are simply unidentified flying objects, all of them probably military.
