Who made up superstitions and when?
As long as there have been creatures able to thnk in an orderly fashion there have been superstitions but my guess is that the first was around 75000 years ago when the first cvilization started as for who made them up think of it this way all things (i wont say humans because we are not the only one capable of consciouss thought) have questions and if no one knows the answers someone will make something up ex. greeks wanted to know why the world worked the way it does and someone decided that it was gods at work thus the greek religion as for your speech try starting off Like this: Greeks romans mayans all of these people have asked questions and in turn have made up superstitions.
