If there was another life form advanced enough to get here, they’d likely consider us an unwanted parasite. I think we may be better off if none ever show up to check us out.
No I haven’t seen any, no I don’t think ANY have EVER visited(Zecharia Sitchin’s theories not withstanding). They do seem to visit rural areas after a few to many PBRs though.
I’ll still enjoy a good s Sci-Fi movie with a few space creatures mixed in at times. I don’t even mind a little Bigfoot talk, even though he/she isn’t real either.
