That you have your own personal definition of the word creation (and other words, as evidenced through this thread) is not conducive to discussion. The word creation is not dependent on physical reality. We only see creation in physical reality because, quite simply, that is all we see. However, if someone says that, as an example, god created angels, would that not be a non-physical entity creating more non-physical entities? Is there any reason, outside of your own unexplained definition of the word, that one cannot say a greater, yet still non-physical, god created the god our our universe? You complain over and over about people nit-picking your word use, but that's because you have your own definitions for things!
I don't have my own definition. Create: to bring into existence. God is immortal and eternal and always existed.
We only see creation in physical reality because, quite simply, that is all we see.
All that we are aware of. I can create a vacuum, you can't see it yet it exists. Still, it is a word we apply to physical creation. I don't know about God creating angels, if I ever see God create an angel, I'll believe that is a possibility. As for now, it's wild speculation that spiritual nature has spiritual creation or that the word can apply to spiritual things.
Hold on, you need correcting again. Theorized singularity does not "precede" the Big Bang. It is the point where the Big Bang
begins. Nothing physical can exist prior to this, there is no time or space for physical to exist.
General relativity applies to our universe, time, space, and perception of physical reality. Without an expanding universe, there is no time and subsequently, no physical reality. As you said, you can't even explain how time cannot exist. Yet, before the Big Bang created the universe (including singularity), time did not exist. If time can't exist, the physical can't exist.
Oh, and if what preceded the singularity is unknown (assuming that anything at all preceded it, and that the term preceded even applies) then what preceded it being non-physical isn't known.
Well since we do know that time creates physical reality, we know that before time there couldn't have been physical reality. Singularity is the beginning of the Big Bang, it doesn't precede it. It's like claiming the dropping of the green flag in NASCAR is an event preceding the race, it is not. It is the event that begins the race.
Long before man knew ANY of this stuff, we had an intrinsic connection to something greater than ourselves, something greater than physical nature. We are aware of this by design. We could have never accomplished what we've done without this intrinsic connection and awareness of something greater.
