In 1947, ancient human remains were found, which were estimated to be 10,000 years old. Discovered by chance during excavations in a "mammoth cemetery", people identified them as the "grandfathers of Mexicans. Soon it was considered a great anthropological discovery, because it was one of the oldest vestiges of the prehistory of the American continent.However, scientific rigor overturned the myth of the "man from Tepexpan." By 1985 it was known that he had not been a man but a woman, And that he had died at the age of 30. If he could speak this "grandmother of the Mexicans," he would surely claim his discoverers to have increased his age: he is only 2,000 years old, not the 10,000 that initially Attributed.
