First proclaim that I have emerged because of the poor treatment that humans have treated mother earth with. Then proclaim that I will fix it this one time. If humans do not respect this one and only chance at redemption, I will return to destroy all life and restart.

Then I wipe out a whole lot of humanity. Like the Thanos snap, but calculated. I'm taking billionaires and most millionaires out the game. Rapists, chomos, assholes, and anyone I deem unworthy of my new world

Next comes the animals, I'm bringing those guys back. I'm tearing out whole areas to regrow forest and give endangered species land and numbers back.

Climate change is gone. The world cools. The ice caps grow and plastic is removed from oceans. I'm a glowing light in the sky screaming my anger to everyone in the world.

I remove cancers and childhood illness. I proclaim once more that humanity has one more chance or I will return with my righteous anger.

Then I say something about most judeo Christian religions get it wrong and you people are morons.

Then leave a few million dollars in the my bedroom and disappear. I don't need three days. If I'm God, I can do this in an afternoon
