What If We Aren't Alone?

Okay, let's say hypothetically that there really is advanced life in the universe. And let's also say that they've found us and have a way to travel millions of light years to get here. To me, it makes sense that the only thing they seem to be doing is flying around looking at things. They seem to only be observing. They seem to only be studying us and our culture. We do this too when we observe animals or fish. Just imagine fish, at the bottom of the ocean and then one of our subs that is sent to explore passes by them. They would probably be really confused. "Did you see those lights?" they would ask each other. "Yeah, that was weird." But then when they tell their friends, the friends would just think they're crazy or making stuff up. My point is, maybe we're the fishes to some alien submarine. Maybe there are creatures out there that are so smart, so advanced, so much better than us that they come to observe us the same way we observe the animals on our planet. Maybe we're someone else's animals.
