Plausibility of ancient extraterrestrials

[Sicnoo0]

For whatever reason, oxygen and hydrogen seem to be the accepted translations of pranavayu and udanavayu 
I'm not the one claiming they were talking about oxygen and hydrogen; the translations are ripped directly from the website.
Any time I look this up, every source seems to agree that one can confidently surmise that - in the greater context of the Agastya Samhita - it definitely seems they were describing oxygen and hydrogen

They knew pranavayu to be a life-giving gas and udanavayu to be a floating gas

Were they oxygen and hydrogen in the modern sense, with atomic numbers included? No. I guess in some sense they weren't referring to oxygen and hydrogen. Instead, we could say they were referring to a vital life-giving gas that we breathe in as well as a floating gas that can be used in balloons

According to his findings, it appears as if this passage you quoted doesn't appear in any of the ancient Sanskrit texts, or rather it's not even a translation of anything written in those texts. Rather, some charlatan in the early 1900s provided a wacko interpretation (not translation, mind you) of some ancient poem, which then got confused by later dolts to be a part of the ancient texts ...

I acknowledge I've lost on this point. Thanks for pointing this out.
