What are two theories about the origin of the greeks?

Elements.

Elements had a natural tendency to separate in space; fire moved outwards, away from the earth, and earth moved inwards, with air and water being intermediate. The Greeks used this rather artificial-sounding theory of the four elements to explain many of the actions of nature.

Hope this helps!
