ok, so aliens figured out the nuances of intergalactic travel and probably skirted the whole 'speed of light' bullshit to come a few fucking miles from the crust of the earth??
if they could get near here they could probably chill out by saturn and just look at us through their cameras/other instruments because their shit would be off the chain
if I was a grunt on an alien ship and the captain decided to get THAT close to a planet, i'd be fucking pissed!!!
