Doesn't wash Hawk........and if I knew the person you describe, I wouldn't argue, just say, "Oh really....Tell me about it." I would then try to supply appropriate noises of startled amazement. This one I have to see for myself. There are way too many variables involved to have the average alien, as generally described, show up on my doorstep.

I would consider it far more likely that a life form has already visited and we had no idea what it was and were unable to recognize it as a life form. It may or may not have recognized us. Kinda' like flattop...............Anyway, go commune with Major Tom about it all and see what he thinks.(:<))
