Game crashing when loading world on 1.7.2 (and also making a world)

What I wanted to happen was for the world to load completely.

What happened was the game crashed.

Step by step instructions:

1.Load minecraft In 1.7.10 or 1.7.9 or 1.7.2 or 1.7.6 (if they even released 1.7.6).
2.Open a world.
3.The game will either crash or load it up completely, I can't show any attachments because of that, otherwise I would have to PRT-SCRN the game crashed. Only reason why it says 1.8.8 up there is because the tag for 1.7 doesn't exist.
