Robert,
I see you still hold to alot of the factoids that the WT used years ago might I suggest that you examine them a little closer for their factual content for instance you mentioned:
Here are a few factoids http://pages.prodigy.net/jhonig/bignum/qland2.html th
What really is a factoid? Here is the def:
1: an invented fact believed to be true because of its appearance in print
2: a briefly stated and usually trivial fact
So factoids generally aren't very useful interesting perhaps but not good at coming to valuable conclusions.
The earth is actually under-inhabited presently. Vast portions of the planet are virtually uninhabited and uncultivated while billions of people are crammed into urban areas.
The planet has about 47 millions square miles of land, which means there are currently about 5 acres per person for earth's 6 billion.
Let's say there will be 25 billion resurrected counting children born into the new world, that would mean, roughly, that each person would have one acre.
First off you and our reader recognize this as reasoning straight from the WT. You, I and the readers need to realize the WT is not really interested in giving fact but factoids that support their already drawn conclusions.
Second these figures are highly distorted as they don't take into account vast deserts and mountainous regions and presupposes god turning every square foot of dry land into a place where humans can live and cultivate for food without much room for anything else.
Thirdly they go on the presumption that man has only been on this earth for six thousand years and so the resurrection figure is low balled to your 25 billion figure.
Scientifically this 6,000 yrs thing is easily proven wrong as the evidence is massive so as to be laughable to any seriously minded person interested in really checking out the facts which I would like to suggest you do, and do it without prejudice and with an open mind unfettered by years of indoctrination you have received from the WT organization.
