Philosophy began by questioning the mythological world view of how humanity was created.

The earliest Greek philosophers are called the Natural Philosophers because they were concerned with the natural world and its processes.

Miletus, a Greek colony in Asia Minor on the coast of modern-day Turkey, was the birthplace of three Natural Philosophers.

Parmenides (c. 540 – 480 BC), from a Greek colony in southern Italy, believed that everything had always existed.
