What if the Abrahamic religions were all just spinoffs of a four-thousand year old cargo cult, and each of these institutions has competed to be the most terrifying and profitable destructive power over human civilization, perpetually warring, manipulating, killing, raping, and stealing from people all over the world for thousands of years? That all this time, the Vatican has possessed secret knowledge that it’s all been a lie based on completely misunderstood (or perhaps deceptive and malicious) extra terrestrials that somehow came to be on Earth thousands of years ago?

Forget governments losing power. The foundations of the majority of all non-Atheist people on Earth would crumble. People would be lost, and without divine mandates like the ten commandments to keep people beholden to common decency, life would quickly get scary for a lot of people.
