We don't have any explanations on aliens becuase there isn't anything to explaine,
there aliens big deal wow! But how they float in their space ships nobody knows. They may
come through a worm hole from a paralel universe who knows. Maybe the the negative
alien came through a worm hole and everyone there is negative and they live totally the same
except there in negative.
Maybe the wobbely skin guy came from the future where everyone gets
weird skin and it may not be considered weird, just normal and maybe they don't have horse
racing or lotto because they would lose so much money through time travel or meybe they do but
you have to have an iq of -200 to enter so they choose the same number 6 times in 56 games
and don't think about traveling back in time who knows...
