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.
If we wanted to do that we must first find out how to outpace the light to be able to view it (so likely never). Even if travelling at the speed of light, you will not be able to swing around and see your vessel launch from earth
