Why do other planets exist?
Because they can.
Since we know that they exist and have developed theories of solar, galactic, and planetary formation that either apply universally or not at all, it is highly likely that whatever specifically causes one planet to form will also cause other planets to form in the same universe.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
