Short answer, to see dinos, you’d need a telescope that has a diameter of 3.4 light-years / 3.2 x 10^16 meters. The mirror alone would need to weigh 100 million times more than the mass of Earth.

Sort of, if their technology is anything like ours they would know there is life here because of our chemical signatures but have no idea what it looks like.
That’s the theory, if they have powerful enough telescope that is.
Think of how disappointed they would be when they got here and it was just a bunch of dumb apes instead of cool dinosaurs.
