How have modern scholars learned much of their information about the Maya?

Archaeologist have studied many of the ancient cities of the Mayas such as, Tikal,Calakumul and Copan. They studied the glyps left behind.

Hope this helps.

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
