Iran and Turkey would be a better place, that’s for sure. Especially Iran was a free country, women rights and everything. Now priests control the country, and women are getting killed for not wearing their clothing “correct”.
Also, the whole western world entered the “dark ages” which was a big push backwards in terms of living standards and science. That was because of religion, so we might be 100-200 years ahead now, if it wasn’t for that.
