So philosophy gradually liberated itself from religion. We could say that the natural philosophers took the first step in the direction of scientific reasoning, thereby becoming the precursors of what was to become science.
The first philosopher we know of is Thales, who came from Miletus, a Greek by in Asia Minor. He traveled in many countries, including Egypt, where he is said to have calculated the height of a pyramid by measuring its shadow at the precise moment when the length of his own shadow was equal to his height. He is also said to have accuraby predicted a solar eclipse in the year 585 B.C.
Thales thought that the source of all things was water. We do not know exactly what he meant by that, he may have believed that all life originated from water--and that all life returns to water again when it dissolves.
