I have been to Chichen Itza and Tulum.....I have seen the Mayan people of today (they are a small people)...by seeing these places, it really makes you wonder how in the H E double toothpicks these people did all of this...The Temple of Kukulkan....is amazing....huge stones......and we were told by our guide that it line's up with the temples in Egypt (never verified).........In my opinion (after seeing these 2 places) there is no way that the primitive peoples could have moved, carved, and placed all those stones by hand. Combine that with the brutal heat and weather, and it equals a
miracle of art and work.....if they did do it by hand, they are better,stronger, and have more tenacity than any one person alive today.
