A scientific theory must be based on careful examination of facts. “A theory is a hypothesis or set of hypotheses that has stood the test and (so far, at least) has not been contradicted by evidence” (Suplee 9).

Thales was both important and extremely influential. He wanted an explanation without turning to supernatural powers. Thales attempted to explain natural phenomena without reference to mythology. Other philosophers admired his way of thinking and followed him in attempting to explain substance change, and the existence of the world. Thales had two strong beliefs. They were that that “nature must be understood without the supernatural and that humans are capable of discovering nature’s truths through observation and reason” (Adler 33). He was credited to be the first to bring geometry and astronomy to Greece from Egypt. He was best known for his supposed prediction of a solar eclipse that marked the end of the war. “He was able to change the course of a river so an army could cross it” (Adler 31). He claimed that the earth was a flat disk and that an earthquake was caused by a wave in the water. He identified water as the basis of the universe. Thales set a trend for fundamental
