<bot>: The discovery of DNA changed the way scientists viewed the universe because it provided a new understanding of how life works. Before this, scientists believed that life was too complex to have been formed by chance. They thought that life must have had a creator. But after discovering DNA, scientists realized that life could have evolved naturally from non-living matter and that there is no need for a creator.
