Concerning propagation of the human spirit/soul
We are to be fruitful and multiply.
Not divide, such as when God breathed into Adam’s nostril’s and he became a living soul, the decedents of Adam are not a dividing up of one big “soul-pie”.
Also, it is not a distribution or allocation of pre-existing souls waiting in line for the next body to be birthed.
It is multiplication of life, much the same way that fire multiplies itself.
