Are aliens hiding in plain sight? (theguardian.com)

They are so, SO, freakin' lost.

Just look closer in the tunnels / craters below the surface for god sake.

If the universe is infinite, then everything within the realm of physics exists, so we should expect that there is life all around us (even on Earth) that we are unable to recognize because of biological limitations in our senses.

Maybe as we begin to augment our senses we'll start to discover all kinds of weird things floating around.
