If the universe were different, then the universe would not be the same. So God must have done it. That's about the sum of the argument.
It is the same flawed thinking that leads many to believe in fate or predestination. I was born as a result of infinite contingencies, I must be an act of God. Then God gave me skin cancer..... round and round Christian theologians spin explanations and excuses for how God can be both responsible but not responsible for the universe. That sun that gives energy to our world is at the same time deadly radiation.
At least the ancient sun worshipers understood the duplicitous nature of their God. The God who gave and took life.
