“but-— what if our space travel technology is more advanced than our government is letting on? Think the aliens might keep a closer watch on us?”
That’s an intriguing possibility. If our space program is more advanced that what we believe, then yes I would think some space faring race out there would be more likely to keep tabs on us. If only to make sure we’re not out to rape and pillage the galaxy.
It would be one explanation for the continuing reports of UFOs in our skies, wouldn't it?
This stuff is fun to speculate on, but I'm like most people - I'm kind of an agnostic about it in some ways. Bottom line - there's what I know, and then there's what I believe.
