What would you do if the chosen sides of the polygon was 4?

The Earth is balanced in a position, relative to the Sun, by gravity
(which pulls the Sun toward the Earth) and centrifugal force (which
pushes the Sun away from the Earth). As it travels in its orbit around
the Earth (a distance of 600 million miles BIG EXCLAMATION MARK),
it veers from a straight line only 1,725,869,000,000 inches every
131,500,000
miles.

This is intelligent design? No. It's baloney, a con. Utter crap.
And where does this crap come from? discovery magazine

Gawd made the natural numbers, all else is the work of homo
sapiens sapiens for homo neanderthalensis and gorilla gorilla
to be in awe at and buy crappy pop magazines. Tell 'em what
they want to hear because they can't think for themselves and
charge them for it. The priesthood have always been rich.
