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.
How about the use of common sense. You made a baseless statement that Paradise would not be so nice...too many people. What facts or even factoids did you offer? None. Zippo. Just an opinion. Nothing more.
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.
No. The factoidial figures are not distorted. The earth has so many square miles of inhabitable space. Period. I think most people are smart enough to realize that there are deserts and mountainous regions. But there are people living right now in the most inhospitable regions of the earth. Eskimos live in the frozen north. Bedouins eke out an existence in the desert. And people live in mountainous areas. Even at that, Jehovah's word through the prophets states the the deserts will bloom. So, God intends to have man reclaim the earth and renovate it. That is what the kingdom is all about.
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.
No one knows how many people have lived and died. 25 billion may be a very liberal figure. Besides, the history of civilization only records 5,000 years of human existence. Anything beyond that it pure speculation. I merely used 25 billion as an example to show that your fears of an over populated earth are totally unfounded.
