Ahhh but extra-terr whatsits (sorry, had a glass of red wine last night and I have a killer headache, can't think!!) are statistically probable.....there are SOOOO many planets and solar systems out there, the odds of there being NO other life in the galaxy is pretty slim! But, I do not believe in alien abductions/ UFO's
I think one look at our barbaric little planet would have those guys not walking, but RUNNING away!
