I am very glad that you broached the controversial question of creation at the CMS Summer School.
The question is often delimited in the terms that you used in your talk: that is, both by science and theology, thus your deferral to science, I would expect, on the scientific questions.
This represents, I think, a profound mistake! The question of our origin is not a scientific question at all. It is, from start to finish, a theological question and its answer has only theological implications.
The question has only become regarded as a scientific one by a sleight of hand to which the church has caved in from the day of its active promotion by Darwin and his supporters in the mid 1800s and resiled from its prophetic function ever since. The great sleight of hand is two-fold: firstly that processes within the creation can throw light on the supernatural act of creation, and that something must be interposed between the word of God and the effects of that word, some ‘mechanism’ to give life to what God has called to be! How extraordinary for a Christian theologian to buckle before the puffery of materialism and its typically atheistic proponents (or unwitting Christian fellow-travellers) and agree that our God needs a ‘mechanism’ to achieve his ends; particularly when he has gone out of his way to tell us precisely what happened in sufficient detail to eliminate the role of any subsidiary mechanism.
And just think what a mechanism might imply for the doctrine of creation itself? It might imply that agency apart from God was necessary for creation: so whence this agency? It might imply that God made something in order to make something else, as though ordinary providence operated in the extraordinary period of the creation, ending as it does with God in his glory! It might imply things that exist that are outside God and outside the creation: some principle, power, or ‘mechanism’ that is uncreated? What does this say, then about God? But what, also, of us? The effect is to immediately de-personalise the creation work and destroy the filial relationship between us and God. We would be the sons of a machine, not God if he interposed a mechanism between himself and us; yet the only mediator is Christ!
Clearly, this opens up a can of worms.
The reason creation is a theological matter, and one of prime importance is because the creation both shows and defines our relationship with God and sets the entire cosmos and all that is within it in theological context: arising only from God, for God’s purpose and reflecting God as ‘very good’, then to be under the stewardship of his creature that is in his image.
Importing evolutionary ideas into this is not innocuously adding a ‘scientific’ explanation, but is mounting an attack on the sovereignty and capability of God, if not his very being; re-founding humanity as a mere assembly of material, and making the cosmos the foundation of being, with person-hood, shown in will and love relationships and actions occurring within this and not prior to it, in the three-person God. Apart from this, it is also allowing a fiction to explain God’s supernatural acts, a fiction for which there is no evidence, any actual evidence cutting off after it has explained the variation in creatures (but not their origin).
I would ask you to re-consider your position on creation and re-take it as a theological question, because those who deny God see the theological issue very clearly and make materialism the engine of their view of humanity. The two do not co-join. Materialism, how ever it trumps itself up, does not mix with Christian supernaturalism. Each places man and the cosmos on utterly different trajectories.
A sermon that deals with this topic which may be of interest is at:

I would also add that to argue for any mixture of evolution and creation removes God from creation: as many published works attest, as does the lack of movement to God brought by expousal of evolution. My posts on de-godding God and the Creation discuss this.
Furthermore, to claim that the text is empty of historical content, but still serves to show God as creator, fails. If the content is inaccurate, then nothing is communicated but puffery, and it is empty of information that relates to the creation in which it is purported to make sense: that is connects with the categories, relationships and common causality of the creation. It is a sad sign of theological neglect to let this hollow argument pass into print, or sermons, which it does from time to time.
