True or false deep within the jungle of mexico and guatemala lie most of the mayan ruins.

The correct answer is - True.

Deep into the jungles of Mexico and Guatemala lie the biggest portion of the ruins of the ancient Maya people. These people are considered to be one of the most advanced civilizations in the so called ''New World''. They were native to Mesoamerica, and were people that had great knowledge of multiple sciences, and were also a very good builders, as can be seen nowadays by their magnificent buildings that are remnants of this once great civilization. They had their civilization's roots in the Olmec culture, and were very influential for the later civilization of the Aztec people. It is still debated about their downfall, but the most accepted thesis is that it was because of long droughts that contributed to starvation and lack of water.
