120 million years ago. If they were looking at Earth, they would see dinosaurs.
On another item, I think it is fascinating that light has no mass, but it affected by gravity!

Actually, no.
Spacetime is affected by mass. Spacetime is "bent" around massive objects. This is why you can see the planet Mercury when it it actually behind the sun. Spacetime is curved by the mass of the sun. Light is traveling in a straight line, but the space through which it travels is curved.
