*Civilization really hasn't changed over the years that much because us humans still break our backs to get to the goal that we would like to accomplish. But there has been maybe a few bit of some changes, we have technology now, we can do a bit more things that we couldn't have done back then in history.
*Civilization changed over time because we needed it to, Because we actually wanted it to. Through the years we worked hard as a slave just to feed our families, so basically civilization changed for such a good reason. Civilization changed for Us.
