the best I have heard is it's a vision of the Incarnation, where humanity (Son of Man) and divinity (Ancient of Days) unite.
Hi in Daniel 7 if you read the context it is very clear that this is the 2nd coming of Jesus as the kingdom that covers the earth and has no end can only come one time. In Dan 2 the coming kingdom is described as a stone cut without hands that descends and strikes the image of mans kingdoms and leaves no trace of them, grinding them to powder which is blown away. The stone becomes a mountain kingdom that covers the whole earth and has no end.
In Dan 7 a pompous one is persecuting the saints and is given a time times and half a time to before the son of man is sent and note that the pompous one is given to the flame and the rest of the beasts lose their dominion but have their lives spared for a season and a time. When you compare this with Rev you see the beast and false prophet are also given 42 months and when the LORD comes they are given to the flame but the dragon Satan is bound for a 1000 years and released for a time to tempt the nations one last time. This again shows the LORD is king over all the earth and indeed the beasts lost their dominion was rev 13 says
The dragon gave him his power, his throne, and great authority. 3 And I saw one of his heads as if it had been mortally wounded, and his deadly wound was healed. And all the world marveled and followed the beast. 4 So they worshiped the dragon who gave authority to the beast; and they worshiped the beast, saying, “Who
is like the beast? Who is able to make war with him?”
5 And he was given a mouth speaking great things and blasphemies, and he was given authority to continue[fn] for forty-two months. 6 Then he opened his mouth in blasphemy against God, to blaspheme His name, His tabernacle, and those who dwell in heaven. 7 It was granted to him to make war with the saints and to overcome them. And authority was given him over every tribe,[fn] tongue, and nation. 8 All who dwell on the earth will worship him, whose names have not been written in the Book of Life of the Lamb slain from the foundation of the world.
Remember when Jesus was tempted by Satan and offered all the kingdoms of the world in a time and Satan said all these are mine and I can give them to whom I wish. The beast is given this power and destroyed by the 2nd coming of the LORD. When Jesus ascended to heaven where did He go? psalm 110 has Jesus as the right hand of the Father.
The LORD said to my Lord,
“Sit at My right hand,
Till I make Your enemies Your footstool.”
2 The LORD shall send the rod of Your strength out of Zion.
Rule in the midst of Your enemies!
3 Your people
shall be volunteers
In the day of Your power;
In the beauties of holiness, from the womb of the morning,
You have the dew of Your youth.
4 The LORD has sworn
And will not relent,
“You
are a priest forever
According to the order of Melchizedek.”
5 The Lord
is at Your right hand;
He shall execute kings in the day of His wrath.
6 He shall judge among the nations,
He shall fill
the places with dead bodies, Zech 14 shows that the LORD comes on a very specific day and that life continues after this day on earth when the LORD is declared king over all the earth. The LORD comes specifically on a day when Jerusalem is being overrun. Dan 7 and Rev also place the 2nd coming when things are bad in Israel. The LORD comes with His saints and melts his enemies. This use of LORD is showing that Dan 7 is equating the son of man to the ancient of days and indeed the LORD is one God in 3 persons and the son of man and the LORD are bother shown as receiving the kingdom that covers the earth and there is no end. The son of man Jesus is the LORD.
