We are often quick to dismiss them as mere fanciful story-telling of primitive cultures but i am not so sure.
For starters, some catastrophes do shine through more recent history:

- https://en.wikipedia.org/wiki/Volcanic_winter_of_536
- https://en.wikipedia.org/wiki/Year_Without_a_Summer
Then, Nuclear Evangelism is a fun idea, proposing a religion teaching us to stay away from nuclear waste for 10k years: https://www.nahomatsuda.com/nuclear-evangelism
Or you can poke around linguistics

The Arthurian legends and Robin Hood are two English-speaking examples of folklore snowballing into what we have today. I bet James Bond will join them in a few hundred year's time.
And then you go look at where there were Denisovans and Neanderthals, and those cultures have mythologies with trolls and ogres.
The absence of evidence is not evidence of absence - in fact, it is speculated that floriensis perhaps hung on much, much later than 50kya ago - and I see no reason the same shouldn’t apply to Neanderthals or denisovans.
On a similar note - cultural memory runs deep. Take hill forts in the U.K. for instance. Commonly accepted as defensive structures. Except… the populations of these places, the topography, all of it, made them pretty crap defences - and the top of a windy hill, far from water, isn’t such a great place to live. So why? My take: the doggerland flood, and cultural memory. When the sea is slowly encroaching, building on top of a hill, building a dyke, a berm, sensible.
5000 years later, still doing the same thing. Why? Nobody quite remembers, but it’s important.
It is fascinating to note that the distinctions are pretty clearcut throughout the vast corpus which implies it was common and wellknown at that time. There seem to be some good parallels to our anthropological knowledge of different Homo species.
In particular, the "Vanaras" were a humanoid ape-like species who have all the human psychological characteristics but with ape-like physiology. This was one source of inspiration (amongst others) for the "Na'vi" in James Cameron's Avatar movies.
It's just not very plausible that hindu mythology is a corrupted record of living with multiple species of hominids. Timeline-wise, it's not much different from claiming that Tolkien's orcs and elves were part of some kind of historical memory of hominids.
I kinda choose to somewhat believe in this hypothesis because it's mighty fun, and makes the past look so much more romantic!
> The vanaras were probably conceived of around let's say generously 3000 years ago.
No, that is purely your speculation since we don't have evidence one way or the other.
> it's not much different from claiming that Tolkien's orcs and elves were part of some kind of historical memory of hominids.
This is the oft made comparison which is a meaningless red herring, since we know Tolkien wrote his stories in modern times (20th century). Not so with Sanskrit literature; they are accumulations over time, first orally and then written down gradually.
One must not be glib in dismissing ancient narratives/myths/stories, and equally, accept it as fact without thought and corroboration (of whatever type).
David Frawley coined "Frawley's Paradox" w.r.t. Sanskrit literature vs. Archaeology, where on the one hand you have a massive corpus of quite advanced texts on various subjects, while on the other hand, you have evidence of advanced civilizations (Indus valley, Harappa etc.) with no decipherable/surviving textual evidence.
If you now consider the various ancient vernacular languages (i.e. Prakrits and Proto-Dravidian) their actual archaeological evidence predates Sanskrit!
It is all highly fascinating and gives one a lot of food for thought as we add to history using modern means. But as i said in the beginning, we should not limit ourselves to archaeology exclusively, but look at the sum total of what a culture says about itself and has maintained over time w.r.t. linguistics/literature/narratives/myths etc.
No, this is pure speculation.
While there does seem to be some commonalities (ancestral) it is also the case that entire species lived in different parts of the world following different timelines and experiences with no knowledge of each other's cultures. Thus not everything can be mapped to common ancestral factors.
That is why Sanskrit literature is so fascinating since there seem to be records of "different types of people" coexisting. Note that i am merely drawing parallels and not that they were actually distinct species of Homo.
It is fascinating.
For what it's worth, there isn't even much agreement on what constitutes a genus or species among professional philosophers of science (i.e. academics who care about giving a principled definition for species/genus), even for those that share many of the same views otherwise (like ur-Platonists, Aristotelians, Thomists, Scotists, etc.).
1) Paleo genomics i.e. DNA study of any surviving material.
2) Statistical study of Human Morphology i.e. variation w.r.t. current day human (and close primates?) biological structures. Eg. Current-day human cranium sizes vary within known limits. So if we find a fossil cranium which is outside these limits then there is a high chance it might be a different species.
3) Fossil dating shows different species (w.r.t. above data) occupying the same geography and within overlapping time periods.
