At 38:45 in this lecture by Thurston he defines a geometry as a an action by a group $G$ on a simply connected topological space $X$ such that the action is transitive and the stabilizer of a point $x\in X$ is compact. How would you construct Euclidean and or spherical geometry using Thurston's definition?
