Where Did Our Ancestors Inherit the knowledge From?

According to few theories that I have come across, the knowledge inherited by our ancestors are from the post humans, post humans are not superior to us or not "Gods" but they are just "us" from the future or from other dimension maybe, its little complicated to understand. Me being a Tamil and from India have come across many shocking truths and revelations of that of saints, yogis, Rishis, leave these concepts behind you because it very big and to understand this we need more time, patience and sacrifice. What i am trying to tell here is, where did our ancestors inherit   this abundance knowledge from, our Tamil Forefathers had immense knowledge and one such example for that is they named the planet Mars as "Sevvaai" - 'RED PLANET' in English at the age where there was no big development in science or technology! Truly amazing. Actually the soil in the planet Mars is red, but our ancestors knew that several centuries ago and named the planet as RED PLANET! so how come they had so much of knowledge at the time where there was not even enough scientific equipment's?

According to my theory(Im no big thinker or genius, but putting my humble thoughts in a simple way), so according to me our ancestors who were genius and those who were brilliant in science and astronomy mostly are Either Saints, sadhus or free spirits who kept themselves away from Earthly desires or kept themselves away from this materialistic or worldly desires, to put it simple those people were free from Earthly bondage's and responsibilities! Yes they were the time travelers! through transcendental meditation, one cannot get this much knowledge through random means, it has to be definitely something beyond our thoughts! They were the travelers and not through cozy space ships or other things but just through    transcendental meditation. Did you know they formed a network through their minds more like a telepathy with the post humans who live far away from us, millions of years further but yet we could contact them through this network, Its called as "The network of the PAST, PRESENT, AND THE FUTURE" and everything is interconnected with one another..........To be continued
