You don't do your "theory" justice with your set-up.
Genesis 1:9, 10 says all the water was in one place = all the land in one place. Dry land = Earth = Pangaea was contiguous in historical times.
Genesis 10:25 says the earth, (land mass) was divided in the days of Peleg = Pangaea broke up while men walked the Earth.
A theory, something you've not presented here, is a well evidenced explanation of phenomena based on independent general principles, not a non-evidenced, ad hoc collection of interpretations of traditional stories.
Does the text of the KJV Bible say what I quoted above?
I fail to understand why you would ask this question. Do you believe that if you can get people to grant part of your synthesis that the rest will follow?
Genesis 2
17 But of the ponderosa pine, thou shalt not eat of it; for in the day that thou shinniest thereof thou shalt sorely learn of thy nakedness.
18 And we all live happily ever after.
