Exciting as it might be; I'm highly skeptical about life on distant planets, or alien encounter claims.
Even if it were plausible, earthlings are simply unremarkable by comparison.
A species capable of crossing galaxies, isn't curious about a race that's only walked on its nearest moon.
Nor one unable to settle its differences peacefully; or who've been such poor stewards of their planet.
We're cavemen, compared.
An object lesson in what NOT to do as a civilization.
