Yes! the First Cause argument has a DNR, do not resuscitate, order. Shouldn't we just let it go in peace.?
Here are the Big Three .
1. Its too special (Pleading). that all things must have a cause is OK. Except God does not need a cause. this contradicts its own logic.
2. It is Ad Hoc. conclusion supported by a premise assuming it was God in the first place.
3. other creation theories are more simple, and not ruled out by physics.
So let us give Aquinas, et al, the peaceful rest he deserves, and DNR the first cause argument.
