FWIW, you are making the same mistake that Nicodemus made. The Greek adverb used, "anothen", means "from above".
Peace be with you.
No, no mistake. Obviously, Jesus WAS talking about a "second" birth, was he not? Nicodemas thought Jesus was talking about a repeat of the "physical" human birth, but Jesus was speaking about - AND he corrected Nicodemas on it - another kind of birth, a spiritual birth, a birth that was "from above" and not physical human birth. So, Jesus did say you MUST be born again and that birth was from above. When we come to saving faith in Jesus Christ, we are born again into the family of God - we become His children through faith and we have a new spirit nature within us. In order to go to heaven we MUST be born again.
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'...
