'There are infinite worlds both like and unlike this world of ours. For the atoms being infinite in number...are borne far out into space. For those atoms...have not been used up either on one world or on a limited number of worlds, nor on all the worlds which are alike, or on those which are different from these. So that there nowhere exists an obstacle to the infinite number of worlds.'
Epicurus (341-270 BCE)
