The word said no other life exists? And that was because earth is the center of or the “purpose of the universe.” Is this correct?
.
That is correct.
When Yehova is done with Earth, the whole shebang goes up “with fervent heat.”
Try reading Peter’s epistles, and the Revelation’s last few chapters.
.
And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
So there is life out there. Just not as we know it
