INKAS BELIEF:
Concept comes directly from Hinduism
In Hinduism,
Inkas worshipped SunGod as "INTI" and celebrate RA+YMI festival
In Inca mythology, Inti is also the god of the sun and a direct ancestor of the original Inca kings.
So INCA KINGS were probably Surya Vamshees (descendants of either Lava or Kusha)
The Inkas actually celebrated two great festivals in the honor of Sun God
One of the celebrations corresponds to the winter solstice period, also known as Inti Raymi. The festival is celebrated on June 21 and culminates on June 24th. Inti Raymi is the most well-known of the two celebrations. The other ritual corresponds to the summer solstice or “Capac Raymi” on December 21.
This comes directly from hinduism:
In Hinduism there are Uttarayana and Dakshinayana:
1. Uttarayana (उत्तरायण)
Sun moves into the Northern Hemisphere
(Mid-January → Mid-July)
2. Dakshinayana (दक्षिणायण)
Sun moves into the Southern Hemisphere
(Mid-July → Mid-January)
So South Americans followed Hinduism to the core.
The Spanish and the Portuguese destroyed a lot of this evidence from South America.
