Isa 45:18
18 For thus saith the LORD That created the heavens; God Himself that formed the earth and made it; He hath established it, He created it not in vain, He formed it to be inhabited: I am the LORD; and there is none else.
(KJV)
I'm not sure why you think that this supports you. All that is said here is that God did not create the earth in order for it to remain empty. He formed it to be inhabited. That's exactly what happened. There's not one word in that verse that even hints at the idea of a world destroyed and recreated.
God parting waters in Gen.1:9 to make the dry land UNDERNEATH appear is not the creating of earth matter. Even when He parted those waters in two, moving one part up to form the heavens, that's given in perspective of the other part of those waters remaining somewhere else. Those other waters were covering the dry land underneath, showing the earth was already there.
Gen 1:9
9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.
(KJV)
Well of course the land was there. It was part of the initial stage of creation. After all, all of that water wasn't just floating in space.
