No, it wasn’t. You ASSUME creation is the start of time, then cite creation as proof God is outside of time.
You cannot assume a proof.
Here is a scriptural citation:
“But when this priest [Jesus] had offered [past tense] for all time one sacrifice for sins, he sat down [past tense]at the right hand of God. Since that time [present tense] he waits [for a future event] for his enemies to be made his footstool, because by one sacrifice he has made [past tense] perfect forever those who are being made holy.” - Hebrews 10
Hmmm...it shows God inside of time. Now, God could have said He is outside of time - that time is not a part of who He is - but God does not. Instead, He had Jesus, having done one thing, now waiting for another to happen.
“And you’re not interested in revelation, either.”
Poor taste.
That's my point about not understanding what you read: it's not an assumption, it's a fact. God could not have called something out of nothing if mass predated creation. Without mass, there is no time, and that is an irreduccable fact that is understood by its definition.
