What year did transportation start?

Transportation began in prehistoric times, with the earliest forms likely involving the movement of people and goods on foot. As societies developed, around 4,000 to 3,000 BCE, innovations like the wheel and animal domestication significantly advanced transportation methods. The invention of boats and the establishment of roads further enhanced travel and trade in ancient civilizations. Thus, while informal transportation has existed since early human history, organized and advanced forms emerged around the dawn of civilization.
