Well, even though I personally don't believe in a flat earth it says in Revelation 5:3 "But no one in heaven or on earth or under the earth could open the scroll or even look inside it."
I believe this is speaking about the dead.
Paul also uses a similar expression in Philippians 2:9-10....."For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name, so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth" (NASB)
The dead will be resurrected to to praise Jesus who calls them out of their graves. (John 5:28, 29)
