Why Do We Count on Ten Fingers?

We count on ten fingers because we have ten of them! Imagine you're a kid learning to count, you start with one finger, then two, and so on until all your fingers are up. That’s why our number system is based on ten, it's just how our hands work. If we had eight fingers, maybe we’d use base-8 instead! Simple as that.
