Yeah but interstellar and time travel haven’t been done, or at least we haven’t observed such.

Flight had. Intelligence has.

Intelligence is an abstract concept, it depends on what exactly one means by that. I have watched a rockets take off from earth. I have never seen a self-aware machine.

What are you talking about?

We have interstellar objects intrude and fly by our solar system all the time, on several occasions.
