yes. they made I think only one that was 40ft. tall.
Ancient Greeks did not make any statues in their houses as you say. The statues were sculpted in workshops by highly trained sculptors. The materials they mainly used for this purpose were fine marble, which was later painted on (it's a misconception that the statues were originally colorless) and bronze. Hope i helped somehow
What is the intended function of any statue? *sigh* Representation for purposes be it remembrance, worship or historic. A Greek named "Phidias" made the statue, in ancient era when Greeks worshiped those gods, and the statue of Zeus is there for the same reasons a statue of Athena was made. Worship. The same way you find statues of Jesus.
yes there are 88 statues in Switzerland
The Christian God may be based upon a reflection of Zeus, but certainly the ancient Greeks did not know of the Christian God or indeed any religion of ancient people upon which based belief solely in one God.
No, Zeus does not have any churches.
yes
Yes.
They were but believed in, believing something does not make it fact.
That depends on the myth, however since the Greeks were sun and sky worshipers, there are more myths concerning Zeus and Apollo than any other gods and goddesses.
Hera, goddess of marriage. Her symbols are pomegranates and peacocks. She is often trying to make hell for Zeus's lovers, but can never tries to make hell for Zeus because he's... well... Too powerful. She never has any children of her own with anybody other than Zeus because she's the goddess of marriage.
Zeus' parents were the Titans, Cronus and Rhea.
Synagogues generally do not have any statues.
