They don't. At least not anymore. They only believed in gods and goddesses in ancient times when things could not be explained. They made up myths to explain things in nature like earthquakes and stuff similar stuff. there probably may be people who still believe in them though.
No, they worshiped their own gods/goddesses.
Yes. The Greek gods and goddesses are still worshipped today.
Yes. Many people believe in Greek Gods/Goddesses. I believe in them.
A lot. The Greeks worship many gods and goddesses so you can't find the exact number. There are many major and minor Greek gods and goddesses. You have to be more specific, how many Greek major gods or how many minor gods.
no they had special powers
No. Any god they could worship would be considered their equal.
The pray with sacrifes of shrines.
Greek gods and goddesses were people which each had their own capabilities ( Ex: Zeus had the power of the lightning bolt.)
it is the temple of worship to all greek gods and goddesses!!!! (BABOO)
Greek gods, and goddesses drank wine.
No Greek gods and goddesses do not "fade"; what fades is the memory of their worship and role in lives of people before more "modern" gods and goddesses. Thus Pan was "replaced" in his role by Hermes and Dionysus, and Helios by Apollo and Selene by Artemis - at least that is how it was seen by those of the Renaissance, to explain why gods and goddesses of ancient people seemed to have overlapping roles.
It's impossible for a mortal to become a God
