First off it would be silly to think that this universe was created with only one species of intelligent life in it. There is no doubt many highly intelligent races with spaceflight capabilities similar or superior to our own, and possibly the ability for interstellar travel. Now I don't want to be redundant,because we have been over this whole roswell thing before and the general consensus was (61%) that an alien craft did in fact crash at Roswell, New Mexico in 1947. Now if infact an alien craft did crash at Roswell, my question is do you think the Roswell "Greys" were friendly or hostile? Where they interested in an exchange in technology perhaps? And no I do not think for a moment that we reverse engineered their technology to manufacture the transistor and integrated circuit, we were well on our way to the technological revolution well before the crash. Or where they explorers that are just as curious as us humans? Or do they perhaps have conquest in mind? I'd like to hear your thoughts and theories and I will post a poll shortly after.
