What is The Flat Earth theory?
“It is he who is enthroned above the vault of the earth and its inhabitants are as grasshoppers”. (Isaiah 40:22)
Just to be clear this is not a religious movie, but I thought the description describes the Dome (the Firmament), as a Vault. And that how the Inhabitants that live above the vault. See us humans as mere Grasshoppers. So who built the dome and who resides outside the vault.
