How 'bout another planet smashed into earth (like how the moon was created) and smashed a lot of mass off, and a lot of that turned into minmus and humans had to migrate into the water because land was inhabitable?

You did say that the kid both kicked you to the floor and punched you pretty hard. Sounds like him attacking you first. Definitely tell an adult before acting out though.
How much bigger than him are you? That also influences what you should do if adults do the usual thing and say something like "It sounds like a simple problem, I bed you could solve it yourself". If you're huge then tackle him.
