Binaries

So why does it seems like everything in the universe is organized on a binary scale?

civilization vs nature
man vs womam
light vs dark
us vs them
spirituality vs materialism
day vs night
right vs left
thesis vs antithesis
life vs death

Is there a materialist answer for these binaries? I actually do there's gradients in between but there is always poles of existence.
