A great awakening
For most of us, the history we learned in school and the history that is most commonly portrayed is really a whitewash over what really happened. In part this is because people have no way of knowing exactly what happened and for others, well, they couldn't care less because they are only focused on their survival.
While there is evidence of human habitation on all the continents pre-dating 100,000 BC with underwater cities and habitation sites pre-dating the end of the last ice age around 10,000 BC, it's relevant to clarify some key points. Of significance is the lion-man image dug up in Germany dated to 40,000 BC and a solidified mercury Vishnu statue dated to 26,000 BC which throws a spanner in the works of many historical scenarios.
Estimates for the global population range between 2 million and 10 million human inhabitants based on archaeological evidence. It seems probable that there would have been a degree of global communication even though travel time between regions may have been measured in years which would help to account for the different narratives occurring in regional folklore and religion.
This is a period when the ice age was ending, the worlds deserts are yet to form and the big melt is yet to happen. Dwarka on the Indian continental shelf is still high and dry, and it's part of an extensive network of cities referred to as the Indus Valley civilisation stretching up into modern Pakistan and beyond present-day New Delhi. (The Sunken City of Dwarka is dated to the time of Krishna)
Legends tell us that about this time Lord Shiva as the Adhi Yogi (the first Yogi) transmitted the secrets of the universe to the Saptarishies who then travelled to the corners of the earth sharing those teachings. If such men were to travel, they firstly had to have the knowledge that there were places with people to travel to and there had to be a means of travel because it is said that one of the Saptarishies went to South America.
If we accept this as very plausible if not actually factual, then it helps to explain many shared concepts and reverence for life amongst indigenous peoples although we should also bear in mind that the nature of existence is freely available to all who seek.
While there is some evidence of ancient civilisation as well is many human types in Africa, this seems to be no clear consensus as to the nature and timing of their development. In contrast we know that the British were still hunter gatherers although it seems likely that with the UK still connected to what is now France those people who would eventually become the English remain as hunter gatherers while agriculture was developing across Eurasia and possibly Southeast Asia.
Australia remains something of an enigma because of the way the British decimated the indigenous population and without trust, the indigenous peoples could not share their stories and what stories they did share, the colonialists lacked the mental capacity to understand.
Meantime the islands of Japan were about to gain their independence from what is now the Chinese mainland, but the people were sophisticated and produced ceramics which means that they also must've had some form of agriculture and technological development.
It seems probable that Maritime adventures were beginning in the Mediterranean with communication links as far as India with population growth and the development of civilisation across Western Asia along with the creation of the structures at Gobekly Tepe.
While the Arctic region extends ice sheets down over substantial parts of North America, Europe and Russia, this ice coverage is not uniform allowing people seasonal access in the vicinity of the ice. But while most people were still hunter gatherers, there were pockets of civilisation and what is now India and Japan it may have even had communication links.
While there are other historic anomalies indicating periods of civilisation and sophisticated technology before this time, this is really start of the modern era where Sanatana Dharma began to spread across the world only to be snuffed out in many places by colonialism and the spread of the great unwashed.
