The civilization that was the first formed in Mesoamerica is the Olmecs. Here's why:
1. **Historical Importance**: The Olmec civilization is considered one of the earliest complex societies in Mesoamerica, dating back to around 1400–400 BCE.
2. **Influences on Later Civilizations**: The Olmecs are known for their impressive art, monumental stone heads, and advanced agricultural practices. They laid the foundation for many aspects of later Mesoamerican civilizations.
3. **Cultural Legacy**: The Olmec culture had a significant impact on subsequent civilizations in the region, such as the Maya and Aztecs, influencing their art, religion, and societal structure.
While the Maya, Toltecs, and Aztecs are also important Mesoamerican civilizations, the Olmecs hold the distinction of being the first known major civilization in the region, making them a crucial piece of Mesoamerican history.
