As an alien observer orbiting Earth what could be inferred about our planet?

i doubt they would be able to comprehend what we are, so, they would see vast amounts of the planet not inhabited, and the parts that are, they would see us like we see ants, wondering what we are doing. they would see us going to work and see our homes, but they would not understand what we are doing cause they are probably not of the same body as we are, nor have the same needs and their homes would probably not be anything like ours. So, we would just look like a bunch of ants.
