I thank you for your thoughtful reply.
The very structure of our universe is a sort of oscillation of energies. Take for example if you view a light bulb through a very slow motion camera of many frames per second, and you will see the light "flicker" as light itself is a wavelength and nothing that is on all the time. The same goes for the greater cycles and oscillations, including our own cycles of consciousness.
The ancients understood this innately.
As far as the long-lived lives in the bible, I think perhaps the "years" was mistranslated from "moon cycles" perhaps. I personally do not feel that a human's life can go very far beyond 120 years (but I'm always ok with being wrong about this).
