Nice spin, but your wrong. Nicodemus even asked how a man could go back inside his mother's womb, and Jesus rebuked him saying " Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.c]">[

You are trying to downplay the role of baptism in our salvation. If Jesus did not mean baptism in this, but meant natural birth, then why did Jesus go and become baptized by John in the river?
Matthew 3:13-17, and why after Jesus was baptized did God declare Jesus as his son when (of course) Jesus was His son since the very beginning of time?
It's simple, we are to be baptized "in water and spirit" or we cannot enter the kingdom of God.
