When we look out with our most powerful telescopes, we don't see anything.

Fermi's Paradox (Where is everyone?)

If Aliens visited 150 million years ago and found dinosaurs, they would have left an obelisk or some other marker, or left something in our orbit.

We are alone. Accept this fact based on the evidence.

In the 3 billion years that this planet has supported life, some civilization should have passed through and left something (even accidentally), yet we have nothing.
