That's not _too_ unreasonable a belief. After all, _we_ exist.
Therefore, it is possible for intelligent life to evolve, it is
possible for life to originate on a planet.

So, if this is possible to happen naturally here, it's possible
elsewhere.

And the Universe is a very big place.

It's just that we have no way to know just _how_ "not alone" we are.
Are there hundreds of civilizations in the typical galaxy... or is our
civilization the only one, not only in this galaxy, but also for
hundreds of galaxies?

And in the latter case, if it's also true that faster-than-light
travel is utterly impossible... first contact may be a long way off.
