I don’t understand why you lump the Big Bang Theory and Darwinism together. The picture painted by the data concerning the changes that have taken place over more than thirteen billion years most definitely fits the Genesis narrative and it does not require mental gymnastics to describe it as such.
Summarizing the process, from nothing, whether or not the first instance of time was a singularity, the entire universe was at its earliest stages a plasma - undifferentiated material being in the form of light. After that first “day” of creation, utilizing that light or primal matter, whatever one may call it, subatomic particles were brought into being and joined together into greater wholes of hydrogen atoms which, in the myriad of suns that developed, went on to bring into existence atoms with greater mass. These in turn. formed the planets. That star dust was utilized in the creation of life. Whether single cells, plants or animals, these are all expressions of a new form of being, to some degree having not only a physical dimension, but also instinctive perceptions, “interpretations” of those “sensory” experiences as well as behaviour patterns, all united in the reality of their existence in themselves, which was and is in relation to their environment.
Ultimately, we find ourselves as the crown of creation, a creature, a unity of perception, knowledge, feelings and action, 100% spirit and 100% matter, capable of knowing its maker, capable of love. I would place more value on the Biblical report that creation took place over six “days”, than how we structure the changes that occured in the universe from the Planck Epoch until the advent of mankind. Genesis does a far better job at conveying the reality of creation, the fact that it was done in a step-wise fashion, utilizing what had been created to bring into existence new forms of being ex nihilo.
