oy...Thank you Isis. I'm too slow to respond.
yes this is what I'm referring to. This might be a long post. Okay...
2 Peter 3:5-7*(New International Version)
5But they deliberately forget that long ago by God's word the heavens existed and the earth was formed out of water and by water. 6By these waters also the world of that time was deluged and destroyed.

The Bible says that the earth was formed "out" of water, which could be many things. Some think (and there's evidence for) there being some kind of layer of water or mist that surrounded the earth when God created it. This layer of water would have caused a green house effect. (Think of an EXTREME tropical environment, and that's the green house effect.) Basically, in such conditions, the amount of oxogen in the air would be TWICE of that today. So not only would this cause plants and animals to be MUCH BIGGER, but it would block ultra violet rays (causing things to age a WHOLE lot slower.)
In these conditions man would have been able to run MILES without getting winded...yes crazy, and since the sun was blocked and the air was oxegen saturated, healing time would be dramatically sped up. With these conditions it would be easy for man to live HUNDREDS of years old, and other organisms as well. Some think that dinosaurs are simply lizards that lived to be 900 years old.
So what's happened to the firmament? Well...it fell when God judged the earth with the Flood.
Okay....so the firmament fell during the Flood, but that couldn't have POSSIBLY flooded the ENTIRE earth....
Genesis 1:2*(New International Version)
"Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters."
Psalm 136:5-6
"who by his understanding made the heavens,
His love endures forever.
who spread out the earth upon the waters,
His love endures forever.
Genesis 7:11-12
In the six hundredth year of Noah's life, on the seventeenth day of the second month-on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. And rain fell on the earth forty days and forty nights.
The Bible also talks about the earth being spread upon the waters, or the actuall crust being set on water.
There's geologic evidence of there being big holds of water underneath the earth's crust thousands of years ago. It's not there anymore because during the flood, the "springs of the great deep burst" open. We realize that it could not have JUST rained in order to flood the entire earth, so this makes sense. Many believe the fault lines that lay on our ocean floors is where the surface cracked open and the "springs of the deep" bursts open, flooding the earth. It's a lot more probable than the plate techtonics theory. (Even TODAY when drilling for oil, it's been known to come across WATER, and lot's of it, deep into the earth's crust.)
A lot of people ask why God chose a flood to destroy the earth....Easy...It's leaves EVIDENCE: Fossils, erosion, the Grand Canyon, caverns...While evolutions look at that and say that millions of years created it...many look at it, and say a great flood created it in a matter of days.....If not hours.
Anyway, I'll continue later. I'm getting tired. Or questions, it's easier to cover that way...
