The natural man, his body and soul, was created in Adam. All our breath is from that breathed into his nostrils on the 6th day. Creation is not ongoing. We don't think creation is ongoing when new bodies are formed. We see it as the ongoing process of living cells, like apple trees bearing apples and growing new apple trees.
There is nothing to indicate that it is not the same way with the spirit of man.
To go beyond that is to go beyond what is written. The idea that "becoming human" is a process of the salvation of a pre-existent souls is superstitious claptrap.
One wonders why IoDebar is so hawkish on proving the Mormon doctrine of pre-existence?
God uses the formed because we are of the earth.
Gen 2:7
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.
Gen 2:8
And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed.
Your ignorance is showing, Mormons consider those on earth to be part of expanding Heaven. similar to Islam. They do not believe in souls as we do.
We are the bad guys in the story. We are condemned already
