1:9 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.
Your claim is that this passage specifically means that all dry land must have also been in one place, and that no other meaning is possible.
Yet the passage does
not specify that the dry land was all in one place.
Your claim requires the Bible to be more specific than the text actually is. The text very plainly leaves open multiple geological possibilities, simply because
it doesn't specify anything about dry land other than that it existed.
If I say "33% of the Earth is covered in dry land," I've used similar terminology to the Biblical passage...and yet the wording equally well describes Pangaea or the seven continents we see today or any number of other possible configurations.
Your claim simply isn't supported in the text, ICANT.
