Who was first olmec or Maya?

The Olmec civilization is considered to be one of the earliest Mesoamerican cultures, flourishing around 1200 to 400 BCE, while the Maya civilization developed later, around 2000 BCE, but reached its peak between 250 and 900 CE. The Olmecs are often referred to as the "mother culture" of Mesoamerica, influencing subsequent societies, including the Maya. Therefore, the Olmecs predate the Maya in terms of significant cultural development.
