Most certainly yes. But we have zero chance of ever meeting them. Space is too vast and we will never escape our own galaxy I think.

Fp edit: send nudes ladies

Or another option is that they don't communicate using devices based on electromagnetic radiation

The more terrifying thing is that it's probably very unlikely and every other possibility is bad., very bad.

These are all explanations for said paradox. Fermi & Hart both posed the question,”Where is everybody?” These are just a few likely theories

No explanation is needed. We've looked at an extremely tiny portion of the universe, for something we don't know the odds of.

that is one of the explanations and one of the more viable ones but there are many

They weren't interested in humanity, just our stable solar system. And we could broadcast the location of any nearby stars to make sure.
