Plato said that men could see only shadows on the side of a cave that bore no resemblance to what created them. He believed, apparently, in a pantheon of gods. That you wish to refer to his acolytes to 'prove' monotheism is batshit crazy.
Plato believed in a Creator, the Demiurge, or Craftsman, that was the ultimate Good. He may have had some vestigial belief in the generic godlings that he has his characters speak of, especially Socrates, but he has Socrates defend himself from the charge of atheism by claiming he believed in the One, objective Good.
"From this passage we could make some educated guesses about Plato's and perhaps Socrates' positive conception of the gods: the gods are perfect beings, with perfect bodies, far more beautiful than our own; they cannot be killed--in fact, they cannot be harmed in any way. Their bodies are incorruptible. What is more, since they do not die, they need not replenish their population; thus they do not beget child gods to whom they might need to tell stories."
"A brief remark later in Plato's
Republic is also informative. Socrates is about to introduce a famous comparison between the Sun and his highest Form, the Good."
Homer's Gods, Plato's Gods
"The cosmos cannot be eternal, as a Form is, since it comes into being. But it is as much like a Form, as close to being eternal, as it can be (37d). When the Demiurge created the universe, he also created time."
Platos Cosmology: The Timaeus
Platos Ontological argument for the existence of the Demiurge as the ultimate objective Good, as the Creator of all types and the ultimate Good was the seed for monotheism though he still believed in immortal godlings, the latter of whom are fairly close to the Judeo-Christian concept of Angels. This belief in monotheism was fully embrace by Aristotle.
Aristotle on the existence of God
Aristotle, as I understand him, does not attack the concept of the many godlings that are not the Demiurge or Ultimate Good, but he seems to generally ignore them as of small importance.
The Emanationist school of philosophers had gone into quite a bit of detail in describing this concept of the Creator started by Plato.
"The primary classical exponent of emanationism was
Plotinus, wherein his work, the
Enneads, all things phenomenal and otherwise were an emanation from the One (
hen). In Ennead 5.1.6, emanationism is compared to a diffusion from the One, of which there are three primary
hypostases, the One (ἕν,
hen), the Intellect/Will (νοῦς,
nous), and the Soul (ψυχὴ τοῦ παντός,
psyche tou pantos). For Plotinus, emanation, or the "soul's descent", is a result of the Indefinite
Dyad, the primordial agnosis inherent to and within the Absolute, the Godhead.

This concept of the ultimate Good, the Demiurge had no tradition or definition among the Greek poets, and so the Athenians often referred to the Demiurge as the 'Unknown God' for whom they built an alter in Athens.
When St Paul journeyed to Athens it struck him, as a Jew, that some Gentiles could be so pious. He then says in Acts of the Apostles in chapter 17,
22 Paul then stood up in the meeting of the Areopagus and said: “People of Athens! I see that in every way you are very religious. 23 For as I walked around and looked carefully at your objects of worship, I even found an altar with this inscription: to an unknown god. So you are ignorant of the very thing you worship—and this is what I am going to proclaim to you.
24 “The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands. 25 And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else. 26 From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands. 27 God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us. 28 ‘For in him we live and move and have our being.’ As some of your own poets have said, ‘We are his offspring.’[c]
29 “Therefore since we are God’s offspring, we should not think that the divine being is like gold or silver or stone—an image made by human design and skill. 30 In the past God overlooked such ignorance, but now he commands all people everywhere to repent. 31 For he has set a day when he will judge the world with justice by the man he has appointed. He has given proof of this to everyone by raising him from the dead.”
And this began the great conversion of the ancient Greeks to Christianity, whose concepts had such similarity that many believe that Christianity borrowed its concept of God entirely from the Greeks and abandoned its Jewish roots all together.
The point of all this is not to prove God's existence, at least not yet, but that the ancient Greek rationalists not only found the concept of God rational, but actually explored concepts that were very similar to the Christian concept of the Creator.
So for you to claim that Abrahamic faiths are irrational and their believers insane does nothing more than to show your ignorance and arrogance at passing judgement against things you have no clue about, dude.
