Aliens would not be on our side

Think of the classic concept of "Aliens" -- the SciFi Martians,
perhaps -- those aliens couldn't exist. We'd have nothing
of ours that they'd want.
Information? Data? I suppose that's possible. But it's ridiculous
to think of aliens crossing the vastness of space for our natural
resources.
Imagine the cost, even in just resources, to travel all the way
here, collect & store whatever resources you were in need of,
then transporting them back to your home planet... the
investment would represent orders of magnitude more than the
return. Unless...
Unless you saw "Independence Day."
This is a scenario that works, I'm afraid, perhaps the only
scenario that works.
To colonize Mars or even our moon people would have to be
effectively isolated from their environment. They'd need to
live in a bubble, shielded from their world and it's atmosphere.
So why bother with Mars or the moon? Just build that bubble that
the colony needs to live in, slap a couple of engines to it and
you have a space colony.
THAT is a formula that works. And THOSE are aliens that might want
our resources.
So, no benevolent aliens coming in peace, guiding us to a golden
age. That's just fantasy. No, if aliens came here that means that
they have colonized space -- not planets but space itself -- and
roam the cosmos in search of resources to allow them to survive
and even to grow.
COLLECTIVE STUPIDITY
We look at insect intelligence where the individuals possess only
the most basic intelligence yet collectively they build complex
structures... our aliens would be the opposite. They would be
intelligent, civilized beings, perhaps far beyond us in intelligence
and certainly beyond us in knowledge, yet collectively behaving as
an infectious bacteria or even a virus.
Think about it.
