Was Ancient Greek Religion originally Mono-theist?

If i'm correct , Plato Aristotle and Socrates mentioned one real God and they are considered by Greek Orthodox church as a kind of saints(i'm not pretty sure but i can still remember a wall painting of Fotis Kontoglou when those three were depicted as typical Greek orthodox saints). Socrates Aristoteles and Plato in order to "fight" the Gods of the Athenean democratic society , the mythological ones ,manufactured the god of metaphysics and ideology, that was connected with the theories of philosophers and the sovereigns of oligarchy.Thus, the god of metaphysics is absolutely spiritual, is impersonal, a being that in his has a group of abstract ideas.

Complete text for the Golden Bough? It has been called one of the longest books in the English language! Some criticize Frazer�s work by saying he was an armchair traveller and had never been to any of the places. Such critics miss the point of this important study. He pulled together many threads from all over the world to show the �sympathic magic� common among all people in a story telling way (that in my opinion) has never been equalled since before BBC TV documentaries.

 He was most criticized for talking about vegetation gods that live, die and arise again with the seasons. It was not politically correct to talk about such things and it still isn�t, so the best of his findings were glossed over without intellectual debate. Margaret Mead attacked the works of Frazer, yet many her tainted works have now been dismissed.

 Having a god as such is still not a reality in many countries. Those who want to investigate the subject further could start with Eastern religions, like Buddhism and Daoism. They have a �heaven� called the Pure Lands that exclude none, one works their way towards the state of ultimate bliss by becoming enlightened within the self. I am not recommending any religion here, but point out this worldwide way of religion has developed quite differently from so-called animism to having a so-called deity.   

 This directly links to the topic.  It may be difficult for some to understand but the early ancient Greeks (not the later) had a heaven before they had gods to fill it. Much like present day Eastern religions heaven basically lay within the self and beyond the borders of the realities of which this would imposes.
