Theory says that, a day of The God Brahma is 4.32 billion earth years long. Also, for the creator of whole universe, we must be of microscopic nature. So, our actions, sorrows, joys etc must be too fast and too small for him. This situation is similar to human controlled fermentation. We add yeast to the solution. So, we are creator and controller of their world. But we hardly care about what individual yeast is up to. We only care about quality and quantity of liquor produced.
P.S.: I am not sure if I am theist or atheist. I support concept of God with help of science. So, I support theism using atheism
