==== Even way before the crazy huge numbers: ====
* The surface of Earth is finite.
* You can only pack so many humans onto it before: - There’s literally no space left to stand or breathe. - You’d be stacked on top of each other in towers of people.

Even if you packed people like sardines, you’d hit:
* Maximum crowding in just a few doublings.
* After that, you can’t physically fit that many human-sized bodies on or near Earth.

So what happens?
* People would have to be off-planet, or crushed together, or just… physics breaks.

Realistically: massive crush, instant disaster, everyone dies very early.
