A football is a prolate spheroid, and it's shaped that way because that's also the shape of an inflated pig's bladder, which is what the first footballs were made of. Soccer balls were also made of pig's bladders, but as soon as technology permitted, those balls got rounder, which made them easier to kick.
Why is a soccer ball shaped the way it is?
Soccer balls were in fact made from pentagonal and hexagonal panels, because manufacturers discovered that the combination of these two components fit together precisely to form a perfectly spherical shape which holds its form when kicked.

Footballs and Ellipses
Football and rugby are played with balls that are based on ellipses. An ellipse has two axes, a long major axis and a short minor axis. When a solid is made by rotation around the major axis, it is called a prolate spheroid, the shape of a football.

Players needed a ball that was less round and more aerodynamic. The ball was reshaped from semi-round into a prolate spheroid.

Well, it turns out that the football was never truly designed, it just sort of happened.

Most modern Association footballs are stitched from 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is the spherical polyhedron corresponding to the truncated icosahedron; it is spherical because the faces bulge from the pressure of the air inside.

Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is mostly round because gravity generally pulls matter into a ball. But the spin of our home planet causes it to be squashed at its poles and swollen at the equator, making the true shape of the Earth an "oblate spheroid."
