When we read in Genesis the account of Creation, we risk imagining that God was a magician, with such a magic wand as to be able to do everything. However, it was not like that.
He created beings and left them to develop according to the internal laws that He gave each one, so that they would develop, and reach their fullness. He gave autonomy to the beings of the universe at the same time that He assured them of his continual presence, giving being to every reality.
And thus creation went forward for centuries and centuries, millennia and millennia until it became what we know today, in fact because God is not a demiurge or a magician, but the Creator who gives being to all entities. The beginning of the world was not the work of chaos, which owes its origin to another, but it derives directly from a Supreme Principle who creates out of love.
The Big-Bang, that is placed today at the origin of the world, does not contradict the divine intervention but exacts it. The evolution in nature is not opposed to the notion of Creation, because evolution presupposes the creation of beings that evolve.
In regard to man, instead, there is a change and a novelty. When, on the sixth day of the Genesis account, we come to the creation of man, God gives the human being another autonomy, a different autonomy from that of nature, which is freedom. And He tells man to give a name to all things and to go forward in the course of history. He renders him responsible for creation, also so that he will dominate Creation, so that he will develop it and so forth until the end of time.
Therefore, the attitude that corresponds to the scientist, especially to the Christian scientist is to question himself about the future of humanity and of the earth and, as a free and responsible being, to contribute to prepare it, to preserve it, and to eliminate the risks of the environment, be they natural or human.
