8. Thales
He is an ancient Greek philosopher who also pioneered in atheism. He declared that everything originated from water and that the Earth floats on water–which just sounds nice. Given the amount of times I have seen rats climb out of a sewer puddle in the subway–he may just be right. He is one of the ancient atheist philosophers who argued that nature is a self-contained and self-sustaining system on its own–kind of like Pauly Shore in Biodome. Because Thales ruled out divine intervention in the creation of the world, he also paved the way to the beginning of Greek astronomy.
“All things are from water and all things are resolved into water.”
