Heaven and Hell must be getting pretty crowded with 70 Billion people already there and many more to come LOL.
I have no idea how accurate it is or how it was arrived at but it’s an interesting number because one estimate of how many stars are in our galaxy is around 100 billion and the number galaxies in the known universe was also that number at one time but it ballooned up to 2 trillion and is now back down to 200 billion. Whatever the true numbers are we might all get our own star or own galaxy if that is a plan God has in mind.
