32. The Invention of Roads
- Invented By: The Ancient Greeks
The invention of roads, considered a major scientific breakthrough, was implemented by the Ancient Greeks. The reasoning for this was that even in open fields, it was hard to travel for military. This could have been due to problematic grown field grass, rocks, and more.

This led to the Greeks clearing out paths and using dirt to remove the grassy issue. However, it was the city of Ur that was responsible for the first stone-paved road, formed around 4,000 B.C. Meanwhile, the Egyptians have the oldest known paved road, which was formed between 2,600 and 2,200 B.C.
