Carl Jung believed that archetypes exist in a universal subconscious shared by all humans. He studied ancient flood stories from different cultures that were similar despite being separated by thousands of miles. These similar stories suggest archetypes explain how humans think in similar ways. The flood stories of ancient Hebrew texts and the story of Matsya from India both involved saving eight people on a boat. The stories also both specified saving animals by sevens and pairs. These similarities support Jung's idea of a universal subconscious and archetypes shared between cultures.
