So, the mayans were ignorant for not having the wheel. Did the mayans have contact with anyone who invented it? I dont think the internet was around back then. So then they would have had to invent it themselves, and it would have been a "new" invention.
The ancient Egyptians had no contact with ancient China, yet amazingly, both civilizations had wheels. Even more shocking, both civilizations used beasts of burden. Also astounding but true, both civilizations realized that animals could be used to bear loads and perform other labor.
