God promises in Genesis 8:22: “As long as earth remains, seed-time and harvest, cold and heat, summer and winter, day and night will never cease.”
He never breaks a promise.
Man may well manage to remove himself, but the planet will remain until God decides it should go. The earth has survived more catastrophes than a global collection of faculty lounge minds can ponder. Setting their clock closer to midnight is the practice of arrogant fools who believe they know Gods plans or could in some way influence the outcome. History is replete with examples of doomsday cults and this one, run by educated elites, hopes to scare up public contributions and Government Grants.
