So did ours.
These stats simply help us quantify what our eyes tell us.
Obviously you can tell by watching the game Cabrera is an elite hitter, but you can't tell just how good he is, or how he compares to the other great hitters in the game (and no, saying he's better than somebody isn't comparing him). These stats give us a better picture of how he compares to them, how much better he is than them, how many more runs he creates then them.
Those are things you can't possibly tell by simply watching.
If you don't care about that stuff, that's fine, by all means just watch the games and enjoy them.
Me personally, I enjoy watching the games, and then looking at the stats to gain as much of an understanding as I can.
