Question

why would early people have been much like house????

Answer 1

Temples overtime developed huge structures, built in shape of step pyramids. But early temple were much like house. They were small shrines made of unbaked bricks except that had outer walls going in and out at regular intervals unlike ordinary building.  Early temples were like a house because:
(i) The temple symbolize the community as a whole and was the nucleus around which the city developed.
(ii) It was here that the processing of produce- grain grinding, spinning, weaving was done as in household.
