Siddhas in America

How likely is it that Central and South America were the intellectual center of the ancient world?  If the Mesoamerican Long Count calendar is what I claim it to be, then this must of necessity be true. DNA evidence tells us the the elongated skulls retreated from Europe to high ground in South America. Is the “race of Siddhas” referred to in the quote below the elongated skulls? Whoever they were, it is clear that Central and South America were not backwaters.
“The Surya Siddhanta is the oldest  surviving astronomical text in the Indian tradition. Some Western  scholars date it to perhaps the fifth or sixth centuries A. D., though  the next itself claims to represent a tradition much, much older. It  explains that the earth is shaped like a ball, and states that at the  very opposite side of the planet from India is a great city where the  sun is rising at the same time it sets in India. In this city, the Surya Siddhanta claims, lives a race of siddhas,  or advanced spiritual adepts. If you trace the globe of the earth around to the exact opposite side of India, you’ll find Mexico. Is it possible that the ancient Indians were well aware of the great sages/astronomers of Central America many centuries before Columbus  discovered America?- the Mayans or Incas.”
