The Contingency Argument for God's existence, in simple language (thread):

When we look at the world around us, we see many things that change. For example, at one time a man may be standing, but at another time he may be sitting. Yet he is the same man. (1/)

Philosophers express this fact by saying that the man's posture is contingent, i.e. that it could be different than it is. Humans are contingent beings because they could be different than they are at any given moment. The same is true of everything we see in the universe. (2/)

Living things like people, animals, and plants all grow and develop. Inanimate things like your car, phone, or computer may be turned on or off. Even rocks and gems can be cut, polished, or moved from one place to another. (3/)

All the things in the physical world are contingent: they could be different than they are.

But is absolutely everything contingent? Let's consider a man who is standing. Why is he standing *now*? (4/)

This question can be answered in different ways. You might appeal to something in the future (he's standing to reach something on a shelf) or to something in the past (he just got out of bed), but we're not interested in these. Why is he standing *right now*? (5/)
