The Coming Alien Invasion is a carefully planned HOAX. The military has been breeding "aliens" in the DEEP UNDERGROUND BASES for decades now. They are genetic manipulations and homegrown "aliens", and not from space.
I have personally spoken to eye-witnesses who have seen them in D.U.M.B.'s, and these sources tell me they are genetic creations, monsters and mutants all made in the bases.
The "spacecraft" are simply highly advanced military flight devices that the US military keeps from the public knowledge...and has kept top secret for decades.
