Ok, I'll try this again. In your conclusion you state that "there is no way that anything will happen without something causing it to happen." This is true, according to natural laws. You say of laws: "At one point, there was nothing. No physical laws". If there were no laws before the Big Bang, then there's no reason to assume that events couldn't happen without cause, that objects couldn't move completely spontaneously. Do you follow?
Whether there actually was a time (or time itself) before the Big Bang, and whether it makes any sense to speculate to what happened before Planck length/time are questions which I'll leave for others.
