“We feel that even if all possible scientific questions be answered, the problem of life have still not been touched at all.” — Ludwig Wittgenstein.  For Wittgenstein, how the world is is  a scientific matter with scientific answers. But, even with the scientific answers are given, we are still left with the fact that the world is.

“And God is causing this effect in things not just when they begin to exist, but all the time they are maintained in existence.” –Thomas Aquinas. For Aquinas, God is not an agent who gets things going and subsequently stands back as they enjoy an existence which does not depend on him. God is “the doing of all being (Timothy McDermott).”
