Probably do some miracles on national tv and populated areas, then create a new book club. Create sanctuaries for book study groups. Assign leaders across the world from those who protect the people.

This time the book is written using formal logic so it’s impossible to misunderstand and pick and choose what you want to follow. It only provides a logic framework of being kind and empathetic to others, respecting their rights(and what rights are), and consent, etc. This time the book will be timeless with no contradictions.

Then kindly “convince” a couple of billionaires and world leaders to donate 99.9% of their wealth to the new cause. 48 hours are too short to change the world for good. But you can kickstart a brilliant process towards a great future.
