Why Do Humans Have Two Eyes?

We have two eyes to see the world in 3D. Think of it like this: if you use just one eye, you can tell what’s close and what’s far, but it doesn’t feel as real. With two eyes working together, your brain puts both views together like a puzzle, and suddenly everything looks life-sized. That’s how we know when something is near or far away, or even if it's moving toward us.
