I’ve had that same talk before about the Genesis “day” as defined by godly not man’s 24 hour clock can be easilly interpretted as involving a great expanse of time.
Hence, the old joke:
A man asks God what a million years is to him, and God replies, “a second.”
Then he asks God what a million dollars is to him, and God replies, “a penny.”
So then he asks God if he could have a “penny.” God answered back, “Yes, in a second.”
