Ezekiel 28 is not about the creation account. In this portion of Ezekiel, the prophet of God has been giving prophecies against the several nations starting in chapter 25 and finishing off with chapter 39 Ezekiel prophesies against pretty much every race of mankind. From chapters 26 to 28 Ezekiel prophesies against Tyre and the Sidonians. In times earlier the Sidonians had been major allies to Israel and Judah in the days of David and Solomon and had trade pacts with Israel and together they prospered greatly, the Tyrians even helped in building the first Temple. Tyre became very wealthy and opulent due to the blessing of God, but through the course of time this wealth and reputation as master merchants became their own snare and vaunted their hearts against God so much so that their princes and their kings began to think that they are God. Therefore, God lifted up a very base people against them and they were destroyed by the power of the Sword.
Ezekiel 28:7-10
7 Behold, therefore I will bring strangers upon thee, the terrible of the nations: and they shall draw their swords against the beauty of thy wisdom, and they shall defile thy brightness.
8 They shall bring thee down to the pit, and thou shalt die the deaths of them that are slain in the midst of the seas.
9 Wilt thou yet say before him that slayeth thee, I am God? but thou shalt be a man, and no God, in the hand of him that slayeth thee.
10 Thou shalt die the deaths of the uncircumcised by the hand of strangers: for I have spoken it, saith the Lord God.
