Human tree is only 6 million years old and most of that time was spent in the jungles. Mahabharata and Ramayana two worlds biggest epics talk about gods and the society 100,000 years ago but not 10 million years ago. And even that could be possible because NASA found what is written in Ramayana about the bridge between India and Shri Lanka, which was named just "Lanka" in Ramayana.
