Because of the force of gravity pushing down on it from ALL sides - and all that "spinning" that it does ;););)

The short answer is gravity. Gravity acts on all mass (and energy too, but that's a different story!). So if you imagine a box planet, the corners of this 'box' are farther from the center than. say, a point on the sides of the box. This is uneven, and it is a natural consequence of gravity to pull this in.
Now, if you take a sphere (and it should be noted that planets aren't perfect spheres) all points are equidistant from the center, that is, gravity is acting on them equally.
I hope that helps!

It is a spheroid. Flat at the poles and bulges at the equator. Due to the angle of rotation and gravity.
