It's like talking about Maya civilization. The experts defending the paradigmas are gonna say the temple of Chaac Mol was the temple of rattlesnake or bat or even a parrot (try to see if the tongue of the rattlesnake comes out of the mouth) instead of saying what is clearly visible here:

Why would they say that? Of course it's cursed to imagine people from Central America before Columbus saw non-existing elephants or that maybe people from Africa or India arrived to Mesoamerica and influenced with Chinese figures in the pots or Lotus flower Hindu positions or dragons and so on...it would be a disgrace for the "patriotism" of the whole nation to admit such a thing! So, even the toys of elephants had to be removed from Jalapa Mexican museum just like Americans do in Smithsonian dungeons with other things.
