RE: PLURALITY OF WORLDS: where the fuck is it!?

Julius,

How do you know that intergalactic visitors aren’t right here in our midst? We’ve seen the cave drawings indicating alien visitors, we’ve seen the HUGE designs in the desert that can only be seen from outer space…we know about those secret govt places…and if they came here, they’d be smart enough to know to hide among us….AND, given our Christopher Columbus era ignorance of other life forms and space exploration, how do you know they aren’t RIGHT there and we simply c-a-n-n-o-t recognize them….like ants on the sidewalk who simply crawl AROUND our foot instead of crawling over it.
