Mythbuster:

"The Maya had many gods and goddesses."

Sort of...

The ancient Maya had around a dozen or so gods and goddesses. The misunderstanding stems from seeing many drawings of gods in Maya art and thinking they are all different, when it is really just one god in different disguises. In addition, the names of gods and goddesses changed through time, so two or three different names can be given to a deity depending on the time period.
