The myans lived in what is now mondern day mexico.
What happend to the Mayans
Where their villages had previously been in what is know asnow modern day mexico.
There were a lot of people living in each of the cities of the myans, this is where they would farm and do there jobs and duties that they had to do to survive.
How did they help us?
after a very long period of time the Mayans left of maybe even have died. there are a few possibility's that are very plausible but we may just never know what happend to the Mayans.
Believe it or not there are still some Mayans to this day.(not original Mayans Obviously) When i say that i mean that they still practice the religion and they even practice blood sacrifices on chickens.
It is pretty cool to think that many of the tings that we use to the day was made by the Mayans such as the modern day calendar that has 365 days in it
To this day it is know as one of the most advanced ancient civilization know to this day, and will live on like that for a very long amount of time.
