Who invented the first road in the world?

the people who built the first road was either god or the Romans or even the tudors but the first staright road ever built was by the Romans.

I heard in many places that the first idea of making road has been discovered by Persian people and the first I heard wad THE PERSIAN ROYAL ROAD.

Persian also are the first people who made the first move-able bridge by number of ships in order to dismantle Persian army into Greece. I believe the idea to build Millennium Bridge in London came from Persian technique in my opinion.
