If the Son is truly God it would have been nonsensical to call Himself the Son and to call the Father God. He could just call Himself God and say there is another God too. The Jews killed Him for saying He is the Son of God so what would there have been to lose, if He was and is God, just to say so. Or just to proclaim a Godhead and identify Himself as part of that Godhead of equals. So it is very significant that He repeatedly called Himself the Son and proclaimed the Father as both God and Father - His God and His Father - and was crucified for doing so. He preached truth so it must simply be because this is true and what God Himself was proclaiming through Him, like He said.
In ancient prophecy the same applies - in Enoch's very ancient prophecy he did not speak of two Gods but always presented one Lord of Spirits - Ancient of Days - and one accompanying Him called the Son of Man with appearance of a human being. Daniel might have known these prophecies and he prophesied the same - an Ancient of Days and one like a Son of Man. The Son of Man was seen in visions being led into the presence of the enthroned Ancient of Days. Not the other way around. Why did they prophesy such things? Because they are the truth.
