I don't have much commentary on this subject except that I had New Age friends in bygone decades who espoused similar ideas.
On the one hand, it is true that there is vastly more to life than what we are aware of. The closest thing to what I consider a trusted source on this subject, the 'automatic writing' of the theologian Neale Donald Walsch, claims that there are thousands of other planets in the universe with intelligent life. Even that seems like a small number relative to the number of planets.
He says that most of these societies are far more advanced than ours. Not only in terms of technology that is science fiction for us, such as warp drives, but also societies that are what we would call utopian - based on oneness rather than money; harmonious with nature, peaceful and free of all cruelty.
He goes into detail about how they operate. Most of their solutions to societal challenges are painfully obvious. He did suggest that Jesus originated from one of these societies of beings who have achieved spiritual mastery. By contrast, the word 'primitive' was used over and over again to describe humans and Earth. I can go into more detail if this topic is of interest to anyone. Though a word of warning; it ends up a bit depressing being stuck here on this planet.
That said, there are downsides to the approach that New Agers take in seeking special labels for themselves. The first is that it can be limiting; the truth of these matters could be orders of magnitude bigger than anything our pea-brains could comprehend.
The second problem is that the ultimate gold-mine of all spirituality - throughout all of history and any regions of the universe - is finding ultimate truth. That profound truth can be intellectually described as oneness or perfect love or whatever, but actually being in that state, enlightenment, is the universal goal. One can only imagine what an entire society of enlightened beings would be like, considering those beings experience an inner utopia regardless of the outside conditions they find themselves in.
The practical pathway is the death of the 'little me' who is trying to be special in a big scary universe. Hence, anything that inflates the ego is a step in the wrong direction. It's a very easy trap to fall into and wastes a lot of time. The goal is death of the false, not making the false self feel better.
