ELI5: What is the scientific purpose of landing on the comet, and what are it's implications?

Besides, you know, because we can.

The purpose is exploration and the testing our capabilities. If at some point in the far future we are going to harvest comets for resources (which would be more practical for building things in space as it takes far less energy to get resources off a comet as opposed to earth) this is the first step in a long process of making that happen.

Also there is basic exploration. We have never been on a comet before, therefor there is a lot to learn about the makeup and development of comets.
