Mexico is the land of the pyramids. There are thousands of them built all over the country. Of these thousands, only a few have been excavated and are available for tourists to see. This is only 5% of their total number. The rest are hidden in the jungle: covered with a layer of earth and vegetation.
Who built them and why? The best minds on the planet are working on this question. So far there is no answer, there are only hypotheses.
We are not claiming another hypothesis – we invite you to become researchers yourselves!
