Early pliers were probably invented many times by many different people.
Wooden, and then bronze, pliers were in use before 3000 BC.
When fire was tamed by early humans, they used a wooden stick to manage the coals. Then two sticks would be used to lift and move hot objects. The men and women would be highly motivated to develop rough tongs and early plier-like tools in order to manage the cooking without getting burned.
Early forging of metals saw the widespread use of pliers for handling the hot metal.

It is impossible to say exactly where pliers were invented. Wherever fire was tamed by early humans, there would be a need for a wooden stick to manage the coals. Then two sticks would be used to lift and move hot objects. Then a partly broken branch with both halves still attached to each other would create natural tongs. Then two sticks would be joined together by wrappings of vines to form rough pliers. Any location that shows early forging of metals can be guaranteed to have seen the use of wooden, and then bronze, pliers for handling the hot metal. Early humans were not stupid. Pliers were probably invented many times, in many places.
