All they do is push the goal post further back to prior physical causation.
In the absence of time, events cannot occur.
Physical causality requires both space and time.
No. The 4d space time of this world is emergent from a higher physics. It appears as a phase change. If you wish to deny that the higher physics always existed, then you must deny the principle of conservation of energy and also claim that A≠A. IOWs null =something. That's not a possibility if you wish to work with a rational reality.
