A little girl asked her mother, “Where did people come from?” 

Her mother answered, “God made Adam and Eve and they had children and that’s how all mankind was made.” 

A couple of days later she asked her father the same question.

The father answered, “Many years ago there were monkeys, which the human race evolved from.”

The confused little girl returned to her mother and said, “Mommy, how is it possible that you told me that we were created by God, and Daddy said we came from monkeys?”

The mother answered, “Well, dear, it is very simple. I told you about my side of the family and your father told you about his.”
