If you are correct then please answer this question which none of your fellow protestants has been able to answer nor even attempted to answer: If Jesus really meant to say born "again" why would he use the ambiguous word Anothon, instead of the word "Palon" which actually unambiguously means again?
The word anothon may seem to us ambiguous but Jesus reply to Nicodemus may have had more than one level of meaning such that a simple “again” in Greek would not convey.
If we are to say “above” is the best or only proper word to use then “from above” in what sense?
