PBS spacetime soft disclosure?

Periodically I watched p b s space time because i’m interested in the cool concepts in physics and science that they talk about.

I have never seen them deviate into such a specific, Is non physics based concept as this before.

Given everything that’s going on, And that PBS receives its funding from benefactors. I’m wondering if this is a form of soft disclosure introduction

“What if humans are not earth’s fist civilization?”
