Plausibility of ancient extraterrestrials

[Sicnoo0]

I got the following from some random site; take it for what you will. I'm having trouble locating exact verses within the Agastya Samhita

अणेन  जलभगोस्ती  प्रणोदनेशू  वायूषू |

एवं  शतना  कुंभना  संयोगहा  कार्यक्ृटसमृताहा ||

Translation: If we use the power of 100 earthen pots on water, then water will change its form into life-giving oxygen and floating hydrogen.


वायुबन्धकवस्त्रेणनिबद्धो  यानमस्तके  उदनःस्वलघुत्वे  बिभर्त्याकाशयानकम्

Translation: If hydrogen is contained in an air tight cloth, it can be used in aerodynamics, i.e. it will fly in air.

The process of air proofing a balloon bag is described as follows:

Dip a silk bag in the bark of trees which produces milky juice (rubber), dry and dip it in the juice of another tree that produces tannin. Dry it again and coat it first with wax and then with mixture of lime and sugar.

Also, I'm happy to admit I've been wrong about the Tic Tac UFO and I feel like my whole life is a lie now

Really, prey tell how you come to believe some ancient text could actually refer to oxygen and hydrogen?

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
