I don’t think so, there is nothing separating the creation of the heavens and the earth from creation week.
There is nothing that ties them together either. God created the heavens and earth before he created day and night, so there could have been millions of years go by before. There are too many assumptions in the young earth reading of the Bible to say must only be 6000 years old.
“...there is nothing separating the creation of the heavens and the earth from creation week.”
Except all of the observational evidence to the contrary, of course!
What Genesis 1:2 states describes an untold unnumbered amount of 'days' literal or figuratively.
