By definition, any aliens who might visit Earth would have to be tool builders / technological and curious. Whales, for example, might be intelligent, but they’re not going to be building rockets and exploring the cosmos.
If there are aliens observing us, their technology could be 1.000 or 5,000 years more advanced than ours. They have little to be scared regarding their own safety. They may be simply curious and want to observe our behavior the way we might observe a species of monkey.

I know I would not want to directly interact when the world was full of Dinosaurs... Could be similar. lol
