re: “Ether”
Ether was a hypothesis developed in the nineteenth century because physicists could not figure out how electromagnetic waves and gravity could propagate through a vacuum. Subsequent generations of physicists figured out how this worked and the “ether” hypothesis was abandoned. This happened roughly a century ago. It is still quite popular with pseudo-scientists and spiritualists.

re: “Mayan Elders”
I find it a bit rich to read of Mayan Elders denigrating translations by anthropologists and ethnologists. That same scholarly community had to crack the glyph language themselves and teach it back to these “Elders”. The language had been lost for centuries.

We absolutely do need to work together to forge a bright future for each other. This will be most effective if we learn to think clearly and accept reality as it is, not as we wish it to be (good or bad).
