The Causer that caused the Space-Time Universe to exist must by necessity exist apart from space-time. Otherwise if he was part of the space-time system, then he would have had a beginning and would also have need of a cause.
Existing outside of the space-time universe solves the problem of needing a first-cause for our observable existence, while at the same time providing insight into the uniqueness of this first cause.
Believers make arbitrary rules that seem to make sense on the surface, then expand to say why God doesn't need to be part of the rules. I am sorry. If there are some universally accepted rules about this, they apply to a creator as well.
Because here's what I can do with your rules. The Matter Energy that became the stuff of this Space-Time Universe must by necessity exist apart from space-time. Otherwise if it (not "he" for it was not living in any way) was part of the space-time system, then it would have had a beginning and would also have need of a cause.
Existing outside of the space-time universe solves the problem of needing a first-cause for our observable existence, while at the same time providing insight into the uniqueness of this first cause. The stuff that created the universe came through a black hole. It existed outside of our space-time universe and none of our laws applied to it before it came through.
You see- I don't really believe what I just wrote above. But it can be made to sound equally as sound as "God existed outside of [whatever I need him to exist outside of to apply my rules.] Instead of God, we use matter/energy. Or we can go the opposite and keep finding a need for a creator of each creator.
OR we can start again. We are here, we don't know why. Let's explore as many options as we can to theorize how our universe began. But we won't get anywhere if we just insist that the book from the ancient goat herders, the one that justifies slavery and treating women as secondary citizens and has stories that clearly are wrong by the evidence, is the end-all of our exploration into the science.
Science doesn't care what Perry believes and facts don't line up for Perry's fairytale. I know, it's hard to accept. But I know you want us to keep telling you this. That's why you keep coming here for us to talk you down from that "leap of faith."
