3. Anaxagoras
A Greek philosopher who mostly did studies about nature and eclipses, Anaxagoras that ranked 3rd on our list of top 10 ancient atheist philosophers and their quotes is also known for his theory that the sun is not held by Apollo as believed by the Roman mythology. When he debated that the sun comes from the fallen meteors, he was called an atheist. He also held that there is “a portion of everything in everything”–so I blame him for balls of yeast everywhere.
“Everything has a natural explanation. The moon is not a god but a great rock and the sun a hot rock.”
