Gen 1: 9-13

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.

So water UNDER the FIRAMENT (HEAVEN) was formed into Earth (vs. 10)

10. And God called the dry land Earth: and the gathering together of the waters he called Seas: and God saw that it was good.

11. And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.

12. And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good.

13. And the evening and the morning were the third day.

SUM IT UP: since the void in vs.1 was split in too is this Earth half the size it was.?
