DOC, if the babble is 'the inerrant word of your particular flavour of god, why are there two different versions of the genesis myth?...
Well the moderator said I could answer your question about Genesis 1 and 2. Your post was long and could take a long time to answer but I will get to it eventually. I will deal with the 1st sentence of your post first where you talk about a "myth". Here is part of what former skeptic Ralph Muncaster said in his 600 page apologetic book "Examine the Evidence" about Genesis starting on page 77.
Step 1 (Genesis 1: 1,2) In the beginning God created the heavens and the earth. 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.
It is important to recognizes the presence of the “spirit of God" at the “surface of the waters”. This frame of reference will be important in considering the remaining steps of Genesis. Science says” There was a beginning of time, space, and matter according to general relativity which was first proposed by Albert Einstein...
Step 2 (Genesis 1:3) And God said, “Let there be light,” and there was light.
Because the spirit of God was hovering over the “surface of the waters”, this reference indicates that light became visible from the vantage point of God – in other words, at the surface of the ocean. Science says : Light throughout the universe would have been available long before Earth developed . However, when considering the language of the Bible, science would agree to the point of Genesis 1:3 – that the next development step, from the vantage point of the surface of the earth, would be that dense gases would become translucent - allowing a small amount of light to reach the earth. This step is vital for photosynthesis, necessary for plant life.
Step 3 (Genesis 1:6) And God said, “Let there be an expanse between the waters to separate water from water.”So God made the expanse and separated the water under the expanse from the water above it. And it was so."
Science says: the next step in development was that heated water would evaporate into clouds. This would set up the hydrological cycle, which is necessary for life.
Step 4 (Genesis 1:9-10) "And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good."
Science says: The next phase of planetary development would be heavy seismic and volcanic activity, which would have caused creation of the continents and other land masses in a proportion of 30 percent land -– ideal for life.
Step 5 (Genesis 1:11) Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds. And it was so."
Science says: Of all the life forms mentioned in the creation account of the Bible, vegetation would be the next step. Light, water, and the large amounts of carbon dioxide that were all present on the early earth would have set the stage for plant life.
Muncaster goes on to describe 5 more steps which I might bring in later as time permits. He then says on page 81
“the ten steps of creation in Genesis agree with the listing of the order of those same events as defined by science. The odds of randomly “guessing” this order would be about 1 chance in 4 million, similar to the odds of winning a state lottery with a single ticket.”
I'll get to your points about the alleged differences as time permits.
