Water water everywhere

So now our little blue marble has day and night.  Starting in verse 6 God starts dealing with all that water. Verses 6 and 7 say:

Let there be a space between the waters, to separate the waters of the heavens from the waters of the earth.” And that is what happened. God made this space to separate the waters of the earth from the waters of the heavens.

The Hebrew says that God separated the waters from the waters.  Now, look up into the sky.  Would you call that "water"?   I guess in reading all of this and thinking about the writing of it.   I know there are those who don't believe that the Bible came from God but I'm looking at these little details.

If you were writing about making sky and oceans would you call the sky waters?  The same word is used in the Hebrew for both waters.  Mayem
   Would you even think about separating the water?  Hmmm?

Well that's what was written.

Also, the word rakea in Hebrew describes what has been put between the waters above and the waters below.  That can be translated as "solid surface".   Hmmm.. now, the land hasn't appeared yet.  The separation of the waters happens on day 2.

 The gathering of the waters happens on day three.

After he has the dry ground appear he has the earth cause seeds to sprout.  Now, the word for dry ground is not the same word that is used above between the two waters so that's not the solid surface.

Another thought I had was regarding when the big flood came with Noah, many wonder where all the water came from.  It must be on this blue marble somewhere because it was there at the beginning.  God had to tuck parts of it away and gather it together for the oceans.  I guess, it all came out of those areas to flood the earth again.  

This is so fascinating
