There are three main reasons for The Mayans to be the most developed civilization from the three. The first one is that they developed a .written language that considered a numerical scale considering zero or absence in i. The second was that they developed calendars that predicted the star movement for thousands of years. The third was their herblore learning and architecture. So good, that has let their building almost intact. As well as allowing them to grow crops in different environments effectively.
The Olmec, Mayan, Incan, and Aztec civilizations are some of the greatest ancient civilizations in history, and yet we know very little about them compared to other parts of the world. The Olmecs are frequently forgotten entirely, and the rest are often lumped together or confused, but they were all completely distinct. In short, the Maya came first, and settled in modern-day Mexico. Next came the Olmecs, who also settled Mexico. They didn’t build any major cities, but they were widespread and prosperous. They were followed by the Inca in modern-day Peru, and finally the Aztecs, also in modern-day Mexico.
Hopefully this answers your question if it doesn’t and I just overlooked it lmk.
