"More than half"
Many fewer, actually; only about a tenth of a percent of those now alive on the earth. Your sources for JW beliefs are seriously out-of-date, if they're not wilfully ignorant. FYI I consider myself in the majority, not in the heavenly .0013.
Please let me address a 'silent question' that's often underlying yours: 'Poor Witnesses; why do you let some old guys in Brooklyn tell you that you can't go to Heaven?'
Answer is another question:
What do you make of Ps 115:16?
"As regards the heavens, to Jehovah the heavens belong,
But the earth he has given to the sons of men*."
At "sons of men" the NWT margin shows six cross-references. See what you make of their application. Then, compare their picture of the earth with the planet we now live on. Do you find the bible's teaching 'comforting?' I certainly do.
*Further, God blessed them and God said to them: ?Be fruitful and become many and fill the earth and subdue it, and have in subjection the fish of the sea and the flying creatures of the heavens and every living creature that is moving upon the earth.?? (Ge 1:2
?When the Most High gave the nations an inheritance, When he parted the sons of Adam from one another, He proceeded to fix the boundary of the peoples With regard for the number of the sons of Israel.? (De 32:
?The righteous themselves will possess the earth, And they will reside forever upon it.? (Ps 37:29)
?For this is what Jehovah has said, the Creator of the heavens, He the [true] God, the Former of the earth and the Maker of it, He the One who firmly established it, who did not create it simply for nothing, who formed it even to be inhabited: ?I am Jehovah, and there is no one else.? (Isa 45:1
??I myself have made the earth, mankind and the beasts that are upon the surface of the earth by my great power and by my stretched-out arm; and I have given it to whom it has proved right in my eyes.? (Jer 27:5)
?And he made out of one [man] every nation of men, to dwell upon the entire surface of the earth, and he decreed the appointed times and the set limits of the dwelling of [men],? (Ac 17:26)
