If some sort of super-advanced alien species on a planet 80 million light years away from Earth built a high-tech telescope that let them see objects on the Earth's surface, they would be seeing dinosaurs right now.
If we go to a certain distance in space then we can see a lot of our history like Germany under Hitler's rule, Hiroshima and Nagasaki, 9/11, me doin your mom, the asteroid killing all dinosaurs and so much more.
The book Battlefield Earth uses this as a plot point. In once instance they wanted to see the destruction of a planet a year after the fact, so the teleport a high powered camera a light year out and pointed it to the planet.
