Along the same lines as the pbs video, I enjoyed Kurzgesagt's video [0] about our ability to sense ancient aliens. [0] ▶ this video 12 minutes
Kurzgesagt did a video on this. Though they discuss how advanced civilizations could have existed on Earth and we might not even know it because there wouldn’t be much left and what was left might be so unusual that we might chalk it up to natural phenomena. ▶ this video
Kurzgesagt also: ▶ this video And just like the paper, it acknowledges the challenges in detecting such evidence due to the limited and complex nature of the geological record.
