How many humans can fit in a perfect world anyway

https://www.earth.com/news/how-many-humans-have-lived-walked-died-on-earth-complex-question/ " approximately 108 billion people have called Earth home.

"

Okay, that is a lot. Over 100 Billion. How many people does Watchtower say have lived on earth?

Because even if it were half that, say 50 billion, would they all fit on earth? Everyone who never got preached to gets resurrected right?

All those pirates of the Caribbean.

So how much land does everyone get in the new system anyway? I assume big cities are a thing of the past?

We all have a cabin like MA and Pa Ingalls? And a farm? Or something else?

Anyone know the current thinking?

Because how could 100 billion people fit on earth? 50 billion?
