Why on earth are you making a false dichotomy between God and Nature? God created nature. Humans have studied nature and created science. God and Nature are different, but not incompatible.
Theology cannot prove the existence of God. The best thing it can do is show that Science does not disprove God.
I have been reading The Big Picture by Sean Carroll in an effort to see why cosmologists reject the Beginning and God. What I found was a whole let of theories and very few cogent facts. What I found was a effort to fit the universe into a particular non-rational framework into which It cannot fit.
I believe following the Bible that God created a rational, knowable world as the home for humanity. That does not mean that we will ever completely understand the universe. That does not mean that there might not be other persons created in God’s Image living in other universes. I am not concerned about what other worlds might be, but only then world that is and the humans who are and the God Who Is Who God Is.
