FWIW, you are making the same mistake that Nicodemus made. The Greek adverb used, "anothen", means "from above".

Nicodemus didn't make a mistake...He knew that to be born from above meant to be 'born again'...And he quailified this statement by referencing the fact that how can he be born twice from his mother's womb...

I don't understand your problem with the word 'again'...

The Greek word, anothen, can refer to both a location, top or above. But it can refer to beginning as Paul used the term when referring to persons ‘at the beginning’.

From the context Nicodemus understood Jesus to be saying “again” as in a repeat and hence a Greek word, anothen, was chosen to translate what Jesus said.

A simple statement, “born again”.
