The Evolution of Religion in a Survival Situation

The religions that died out in nations escaping from Egypt across the desert (in descending order of survival rate):

• The people who liked polyester-cotton fabric mixes
• The people who trimmed their beards
• The people who didn't testify against wrongdoing
• The people who touched unclean animals
• The people who ate fat
• The people with a dodgy tattooist
• The people with an asthma predisposition who thought mildew was pretty cool
• The people who were allowed to eat shellfish
• The people who ate pork 
• The people who ate hoopoes*
• The people who went around cutting themselves in a desert in hot conditions 
• The people who thought God wanted them to eat nothing but shellfish 
• The people who only stole from people bigger than them
• The people that thought they were commanded to settle down and farm on the Red Sea bed
• The priests who didn't wear bells on their robes and made God jump.

* It took them ages to catch one, as they didn't know what it was.
