Eg. if some intelligent life form could do the same from the other side of the universe, would there be any signs of life evident around planet earth? Like could they detect satellites we put up? Or the space station? Or a spaceship heading towards Mars? Or footprints on the moon?

Two issues with that I think. We'd only be able to see it if they happened to have something visible to us at the point in time that we're currently seeing. So it would've had to occur millions or billions of years ago for us to see it now since that's how long it takes for the light to get here. Also even with how much the telescope can see, things that are unbelievably huge irl are still tiny in the image.
I'm not sure how radio waves are observed by comparison though, but I think that would be more likely to detect something?
