He could have done this, but I think it’s a mistake to characterise ‘ensoulment’ as some kind of gene which can be passed to offspring if only one parent has it. I honestly don’t know at which specific point in our evolution we were given a soul.
I think there are indications that our souls developed over time - along with our brains. If we look at increasingly interesting evidence from archaeologists, we will find that gradually evolving humanoids learned to respect their dead - and hence took an effort to bury them. This would imply that they understood there was something special about individuals. They began to make burial objects, cave paintings about life and death. These events, and many others, indicate the
soul, however defined (!) evolved along with those beings who are the earliest in our line, and perhaps even with Neanderthals who were humanoid, but died out after conflict with our kind (we started early!).
Several other points:
(1) recently scientists have noted that there is a lack of fit between Newtonian physics and Eintein’s theory of relativity, which leads them to conclude (without scientific proof, as in the case of black holes as well) that we live not just in an infinite and eternal universe, but in a system of infinite and eternal universes - a multiverse.
(2) Genesis 1 and 2 provide two differing stories of creation.
(3) Genesis 1 and 2 are archetypal examples of ‘creation myths’, those stories that every culture or civilisation develops to explain where it came from, where it is, where it is going, and how it got there. Sociologists, anthropologists, archaeologists are all familiar with such creation myths - these are not myths of your Jack and the Beanstock variety. They are important conceptualisations of beginnings. It is significant that by far the majority of creation myths include the idea of a godhead, a central organising force of some kind, with characteristics that often resemble values, beliefs, the natural environment of the people who recognise that godhead.
(4) I have always assumed that the creation myths in Genesis reflect the early understandings of Jewish tribesmen/women, and particularly their life values. The first five books of the Bible are perhaps part of the creation myth, before we get into historical events in later books.
(5) Finally,
go Google Hubble photographs, for the gallery of photos that have come in from the Hubble telescope. Look at them, and then think for a few minutes about what you have seen, and whether this has changed your perception of creation, evolution, the nature of our God and the gift of His Son, our lives, your religion.
