It’s just a parable to help you understand the age of the universe in light of the scientifically verified Twin Paradox.

“It’s just a parable to help you understand the age of the universe in light of the scientifically verified Twin Paradox.”
Well, if it’s just a parable then it really explains nothing, since you are using a mechanism in the parable (God traveling faster than the speed of light) to account for physical discrepancies. But if you handwave away questions about that using a “parable” excuse, you have also handwaved away any potential explanation that could have been provided.
