Ok, denziens of the planet dirt. For the last and final time, we are not here to probe you. Seriously, if you had to drive for weeks to get to a zoo would you think to yourself, "Thank God, we finally made it. Let's whip out the a-probes and go find us a monkey?" No, of course not. Not unless your seriously messed up in the head. Trust me, any civilization advanced enough to master travelling at speeds faster than light and the navigational expertise to find this tiny little backwater planet in a tiny little backwater galaxy has absolutely no reason or desire to take a peek inside your bunghole.
For the record despite all Mel Gibson movies to the contrary, we wouldn't need crop circles to navigate - I mean if we can find this insignificant planet among billions in your galaxy alone why on earth would we need to stomp corn flat so we'd have some way to find out way around once we got here. Seriously? Oh, and no, we don't need a slave labor force. Do you have any idea of the level of automation required to actually achieve interstellar travel? As for using you as a food source, ick. I mean really, ick. Stop an think about how many bacteria you guys carry around, all of it would be completely "alien" from our perspective. We'd all get sick and die, assuming we could stomach the taste to begin with - which is pretty doubtful.
So, for the record, this nothing more than light from venus reflecting off swamp gas from a weather balloon that was trapped in a thermal pocket. You may now remove your tinfoil hats, untighten your sphincters and go about your business in an orderly fashion.
Lol
