What "primal cause are you talking about?
The Primal Cause is the First to cause.
What do you propose was the nature of existence before this "Primal Cause"? Or are you suggesting this PC came from "Nothing"?
There was no "before" the Primal Cause until He caused it to exist.
Well I can say I don't know safe it the knowledge that you don't know either. There is much about reality we don't really know, isn't there? What matters, IMO, is having the honesty to admit ignorance over proposing ones cherished beliefs did-it.
I don't know "how" but that the Primal Cause caused the universe to exist I do. Why? Because I am part of the universe and I know that I exist and I did not cause myself to exist. Someone that preceded me did that job for me. If the Primal Cause did not cause the universe to exist, who did it, you?
Though there are plenty of hypothesis out there. There is no knowledge regarding the state of existence before the Big Bang eg but it's reasonable, I think, to assume the BB followed from there. All we can really do at this point is look at what we do know and see where that might lead.
What then caused the big bang to happen? Things don't happen out of absolutely nothing.
1. Energy cannot be destroyed or created but can change its state; 2 Time waits for no one; 3 Space appears endless - or if not what might be behind its ending?
Space is what is defined by the distance between matter and matter. Therefore, space is an accident of matter. It was not caused to exist as the solid elements of the universe were caused to exist. The same is the case with energy.
What reason is there to suspect any of that as ever been any different?
The presence or absence of matter in the universe. That's what defines space, time and energy.
How about Quantum Mechanics? Do you have any idea about Quantum Mechanics?
Non sequitur. We have reality for sure but no evidence for whatever this "Primal Cause" might be. We have no knowledge at all of what preceded the Big Bang event.
If to cause things to exist in the universe is not evidence for the Primal Cause, how did the universe cause itself to exist?
Well at least it displays a cordial exchange minus any preaching which is a pleasant change in this thread, so thanks
You ain't seen nothing yet. We are only in the beginning.
