Did our soul exist in heaven before it entered our bodies?

Genesis 2:7 states: “And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.” If there is a “heavenly nursery” where souls would wait for their earthly bodies to be born, then this verse would be wrong. The phrase “man became” denotes a definite beginning where Adam’s soul and body came to life simultaneously.

Our Lord Jesus Christ, is the only baby born into this world who existed before His birth: “In the beginning was the Word, and the Word was with God, and the Word was God” – John 1:1. “And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was” – John 17:5. “And he is before all things, and by him all things consist” – Colossians 1:17.
