How did early humans make and use stone tools?
Long before phones, before metal, before farms, somebody picked up a rock and thought, "I bet I could do something with this." That somebody was an early human, and the rock was about to become the first piece of technology in history. Welcome to the Stone Age, where the cleverest invention started as the plainest thing on the ground.
Here's the trick they figured out, and it's genuinely beautiful in its simplicity. Some rocks, when you hit them just right, break into pieces with edges sharper than your kitchen knife. Flint and similar stones snap in clean, glassy flakes. Nature was hiding blades inside ordinary pebbles — early humans just learned the password to let them out.
