What did the Greeks believe was the source of everything?

Answer 1

The ancient Greeks believed that the source of everything stemmed from a primordial substance or principle. Thales, one of the early philosophers, suggested that water was the fundamental element of all things. Others, like Anaximenes and Heraclitus, proposed air and fire, respectively, as foundational elements. Additionally, the concept of the "apeiron," or the boundless, was introduced by Anaximander, suggesting that everything originated from an infinite, indeterminate source.
