For me, the Maya have always been important because they're our history and our stories in the Americas (I'm from the US) -- more than the greco-roman mythology I grew up with. They grew corn and love ball games. Their stories are more directly our stories, and their struggles are our struggles.
Not to be political, but they also kind of wiped themselves out by large scale environmental collapse, and the jungle is filled with their undiscovered monuments. There's still so much to learn.
People really geek out on how much the Maya knew about astronomy too -- they shot archaeoastronomy docs twice while I was working on site. Richard Feynman even helped decipher Maya glyphs and writes about it in "Surely you're joking Mr Feynman". He gave a lecture also if the audio file can be checked out somehow: https://collections.archives.caltech.edu/repositories/2/acce...
