Important Achievements part 3
I think Astronomy was important to them because they used the astronomy to help predict when good farming would come.
Why did it end?
I think the calendar also has an important roll in there farming, instead of always remembering when farming would grow they would write it down on a calendar.
I think it was cool that they made rubber without any extra stuff in it. They dipped there feet in the rubber let it dry and made shoes.
Theres many different ways they why they came to the end. The first one is is they first could have died from getting a disease, Second they could have ended from war. Third they could have ended from famine, and last disaster or Environmental change.
I believe that they die of warfare, there's many things that can lead up to warfare, but scientist have discovered a cave with a hole much of Mayans in this cave dead, so there's is also a theory that they might have scracvies them selve for a god.
