Every human being has their first birth by uniting the seed of man and of woman.
Unless science interupts the process, a child is brought into this world from that conception, via the mother's womb where it matures to readiness for viable life. Jesus foretold the plan of salvation for this age in talking to Nicodemus. Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. You and I were born human beings, not dogs, or monkeys. As such we will live in this world subject to the limitations and inclinations of human beings.
