Hmmm - I'm not sure what your disagreement is with the Hindu cyclical creation of the material universes. The Vedas state clearly that beyond the creation there is the eternal Kingdom of God - one name in Sanskrit is Para Vyoma, the Supreme Sky. It is stated that the eternal sky, or eternal Kingdom of God, is changeless, is never created, never destroyed, and is actually the reality, of which this world is just like a shadow.
This world exists, but it is temporary, and its purpose is like a reformatory. This realm only is subject to repeated creation and destruction, but the time scale is exceedingly long. The creation and destruction of the material universes have nothing to do with the eternal existence of God's Kingdom, which is in no way affected.
I think we may agree more than you might guess. Atemporarl eternity sounds exactly correct, and God is described as being uncreated, the source of everything, eternally existant.
