I assume they must be out there but haven't visited.
We've been around a blink of an eye cosmically. When we look at the stars in the sky we're seeing light they created possibly millions or billions of years ago. If we tried to visit the star may no longer exist.
If there is a species out there advanced enough to scan and visit most of the universe with relative ease, I imagine they've already visited a lot of lifeforms and we would be primitive and not all that interesting.
