They might very well be out there, but with no interest in going on very long space journeys. They might not see any good reason to leave their planet and go exploring other planets. They might see other civilizations as hostile and dangerous.
I don’t know if there’s anybody out there, but it’s reasonable to think that there is intelligent life somewhere in the vast universe.
“They might see other civilizations as hostile and dangerous.”
