"The Greek philosopher Thales (6th century B.C.) refused to accept supernatural, religious, or mythological
explanations for any observations or events that could be considered natural phenomena (such as origins) and thus set the foundation for naturalism, a philosophy based on the fundamental premise that anything supernatural is essentially fiction. Since, according to Thales, there can be no supernatural cause for the universe and logic does not allow something to cause itself, the universe must be eternal. The concept of naturalism might lead to the explanation of many everyday natural phenomena, but it fails miserably in explaining origins.
