An ant as an individual is smart enough to recognize food and bring it back, do basic social behaviors. However, the real intelligence of ants is emergent from the entire colony.

"They just don't really understand the solar system. And i think it is difficult for them to do."

You could say that about many humans too right now, and certainly all humans up until the last however many years.

Exactly my original point, but referencing those ants who think they know the solar system.

How can you tell? If ants were able to understand the solar system, would you expect them to behave differently?

They would know I exist, and that I would massacre them every time they set foot on my yard, with my advanced chemical weapons of mass ant destruction. But they keep coming, and dying. They don't seem to be aware of me, let alone the solar system.
