Taking our
cue from Tinseltown, I note that most
cineplex
sentients come to Earth either to solve some sort of ugly reproductive
crisis or simply to take over the planet. The former doesn't make any sense
whatsoever. You can't breed with creatures at the zoo, despite the fact that
most of the base pairs in the inmates' DNA are identical to yours (note that
this is a biological incompatibility, and not just zoo regulations).
Taking over
the planet would only make sense if there were something really special about
our world. The best guess of the exoplanet specialists is that the number of
Earth-size planets in our galaxy exceeds tens of billions. That doesn't sound
like our hunk of real estate is terribly privileged.
They won't
come here to mine our minerals, either. The entire universe is built of the
same stuff,
If the type of world that can support life
is rare, then you don't have to worry about nearby extraterrestrials. There
won't be any
