You choose not to understand because it doesn't say GC.
I've never said that Revelation or other scriptures don't seem to be talking about some sort of Earth. I've mentioned this multiple times, and each time you chose to ignore it.
My issue is with the interpretation WT gives to the Great Crowd.
We are going in circles here A Believer.
I urge you to do some research on the matter beyond what WT has to say. You'll find that there are many Christian interpretations out there that do include some sort of return to the Earth by humanity.
Also, research the history of the WT, from multiple sources, and ask yourself if you can honestly say there is undeniable evidence that WT is the one true divinely chosen channel of God.
Also, ask yourself why a supposed loving God would make his word, on which the lives of billions of people rest, so unclear and open to interpretation. If he truly wanted none of children to die, why wouldn't he just make his objective clear, easy to understand and undeniable? Wouldn't you?
