Basketball looks fun, though I don't know much about it.
Let's start with the little you know,then I would elaborate further
There's a ball in it, and it goes into a basket, correct?
Well that's part of the game. Its a limited-contact sport played on a rectangular court.
Oh alright, how do you score points?
A team can score a field goal by shooting the ball through the basket being defended by the opposition team
And how many points does it take to win?
 Goal scores three points for the shooting team if the player shoots from behind the three-point line, and two points if shot from in front of the line.
