Several years ago, archaeologists from the Smithsonian Institution visited Mexico, and they officially declared all these "El Toro" artifacts "inconvenient" and modern fakes (they were made by local farmers!). Mexicans, at the instigation of the Americans, believe the same. You can export them from Mexico as souvenirs, no problem.
The same thing happened with the "Ica stones" (dinosaur stones from Peru) – they are still not recognized by official archaeologists.
P.S. It would actually be a good idea to ask the С's who, when, and why created all those hundreds of artifacts from "El Toro" (and other places) in Mexico. This has been a big mystery for me for many years.
P.S. The "Disclosure" project will most likely begin with Antiquity, as it is most relatable to ordinary people. It is ALREADY integrated into modern culture and art.
