Billions of galaxies with billions of stars in each one?
While I'll grant that there may not be any intelligent life within our
immediate area of the galaxy, also granting that the light speed barrier may just be flat out impossible to break, not only for us, but also for any other alien life, thus rendering us (and them) "alone" for eternity, I believe odds are favorable that there are other species out there.
We may not be able to ever actually meet each other, but we might at least be able to send communication. But bear in mind, due to the light speed barrier, basically, anything that's beyond a hundred light years away just hasn't had a chance to see what we've sent out yet, and that doesn't even account for any signal loss. I saw a image once, that our entire history of radio signals have only crossed but a tiny fraction of the milky way alone.
NASA estimates the Milky Way to be 100,000 light years across, so if you plan to get a signal to the other side in less than one tenth of a million years, you'd have to find a way to send a signal faster than the speed of light... and that's just to
communicate. Actual travel is another matter all together.
No doubt any other alien lifeforms have grappled with the same limitations.
