Okay kiddo, let me explain what Minos is.
You know how sometimes we have rules and we have to follow them so that we don't get into trouble? It's kind of like that for Minos. Minos is a name we give to a group of people in ancient Greek mythology who were in charge of making sure other people followed the rules.
These people were said to be very powerful and important. They were in charge of making sure that people behaved and didn't break any rules. If somebody did break a rule, they would be punished by Minos.
Minos was also said to be a king who ruled over a place called Crete. He had a really cool palace and was known for being a wise ruler.
So in summary, Minos is a group of people or a king who were in charge of making sure that everybody followed the rules in ancient Greek mythology.
