I have been informed about the existence of other civilizations throughout the universe ---yes it is covered indepth in the Sanskrit literatures of India.
BUT I see the topic complicated by other factors...imo:
1] Outer space's temperature is in-habitable. [why does it get colder as you rise ---yet when in situated before the Sun's rays (w/o benefit the "atmosphere's" shading effects]. I would be incredibly hot in Sunshine and below freezing in a planet's shadow!
2] Outer space's absence of Gravity means booster rocket propulsion cannot move itself. [For every action there is the re-action cannot occur when the boosters forces are not countered by friction ---the blast of a booster force pushes against nothing ---so no movement!
3] The earths gravitational field CAN NOT be escaped from! A rocket's force is like a fish leaping out of the ocean trying to rise above to fly.
The rocket is minuscule compared to the mass of the earths gravitational pull. [like a fly trying to escape the whirl of an electric fan. Like a ship trying to escape the whirl of a Hurricane.
Thus, we arrive back to the idea: What about what our Guru's have taught us? Even though, no civilian can confirm any of this unless we go through the auspices of the Guru's compadres.
And also, imo, folks forget what is said about black-holes etc ---it's all theories based on mathematical equations that someone propounded can be conflated with the actual construction of unknown states. Conversely, I'd surmise that the mathematical theories proving the nature of a transcendent soul as the life force of mundane elements has been hidden from western academic publications.

This may be difficult to follow because the translator is constantly cross-referencing other esoteric references [ie; names, places, events, scriptures of Hindu origin whilst expecting the reader to quickly follow along. I suspect that every entry in this tract is copy n pasted from the large tome like texts he translated]
You will find in this tangential publications by a Hindu Sanskrit scholar:
The Demigods; The Universe's construction; The boons of Mystic achievements [aka yoga-siddhis]; The status quo of Celestial beings;
The differential of earth's time zone versus Celestial planetary stratums; The transmigration options of the Soul upon death; The age of the cosmos' creation.
