God and "the Son of man" are not the same being. God is sitting on the throne while the Son of man approaches Him. How could you possibly confuse the two? The Son of man received sovereignty and dominion that he didn't already possess, meaning he isn't God Almighty.
Daniel 7
9I beheld until the thrones were set, and
the Ancient of days sat; and his raiment was white as snow, and the hair of his head, as pure wool: his throne was a flame of fire,
and his wheels burning fire.
13I beheld in the night vision, and, lo,
one coming with the clouds of heaven as
the Son of man, and he came on to the Ancient of days, and was brought near to him.
Out of curiosity, do you hold to a preterist view or do you know that the second advent of Jesus hasn't happened yet?
