Imagine the time when the preachers of the world decided to end the notion there was more than one god.
Unfortunately, those assholes also decided to put an end to Hellenistic and Socratic thought, ushering in the dark ages. The Muslims saw that and thought, "That seems nice!", and followed suit.
Imagine where we would be today if instead of Christianity we pushed truth logic science and reason.
No wars
We’d be mining Mars not our precious planet
No poverty. Only lower middle class, middle class, upper middle class, rich, really rich, really really rich, really really really rich, etc. Same as now just no poverty.
There would be no man made global warming
Abortions would be rare because people can afford to have kids. But still abortion would be legal.
Less poverty means less crime so crime would be rare.
Everyone could afford to retire at age 65
No one would die or be bankrupt because they didn’t have insurance.
