The very fact that the Greek pun of “born from above” and simultaneously “born again” is included in the Received Text indicates the source material being Greek and not Aramaic which as said indicates it could not be not verbatim or an historically truthful conversation.
It also demonstrates the very good chance of early Christian writings being altered at will to conform to higher literary taste and for greater religious impact. Hand written text was ever susceptible to corrupt transmission. Compound this with the impossibility of the words being actually remembered by anyone (let alone false memories) shows that like most of the so called sacred scriptures, they are essentially a literary work, mainly fiction, drawing on older folk tales written by educated scribes in the employ of religious leaders or by those cult leaders themselves.
Thank you for your input Terry.
