What do you mean by "literal"? Do I think it happened as portrayed in scripture and only that? No, that is absolutely absurd. You think all that it takes to make the earth bear trees and fruit is found in the verse "Then God said, "Let the earth put forth vegetation: plants yielding seed, and fruit trees of every kind on earth that bear fruit with the seed in it.” And it was so. The earth brought forth vegetation: plants yielding seed of every kind, and trees of every kind bearing fruit with the seed in it."??
No. A LOT of things must have happened physically for this to occur. That is not just science, it's common sense. The creation accounts are very, very, very ancient traditions passed down thousands of years before they reached Moses (or whoever compiled them) and were committed into writing. How could a primitive man with this vision of creation (or even Adam if they were passed down from him) convey accurately and scientifically all that he was seeing? He simply was not smart enough for that. He had to put what he saw happen into terms and a broadness that he and the ones he related it to could understand. Are we smarter then man 5000 years ago? Heck yeah we are. There is nothing wrong with that. Put a mouse in a room with some simple contraptions and he'll go from knowing nothing about them to be able to use them.
For the record I think whoever began this oral tradition of creation with the vision God gave him (again, perhaps Adam) did a fantastic job considering his limitations. Truly remarkable.
As for the flood, no it did not cover the world. We know that now, a statement many of you find to be a doubt of God but I praise God for the advances we have now in knowledge. The person recording the flood stated it as such because the world was very small to him. (Probably no bigger then Mesopotamia). Where did you guys get the idea that whoever recorded these accounts were infallible super saints? They were used by God. THEY were used by God, meaning who they were. Great men, not God-like geniuses who had a sudden awareness of the entire span of the globe and a huge measuring stick to actually measure how far up the water came to Mount Everest, which by the way was nowhere near Noah and he could not have reached it in 40 days. Was the water fifteen cubits above Mount Everest? No. The author is making a point. Is it then wrong? Yeah, probably. Is the Spirit still the same? Of course!! The authors unfaithfulness (or in this case embellishment) does not annul the Truth of God contained in the words.
Men spoke as moved by the Spirit does not imply accurateness of everything physical, it implies complete infallibility of the things that are spiritual at that time. I have asked this before but to no avail, to those who have spoken in the Spirit did you find yourself with a complete knowledge of physics and biology or was the message of the Spirit transmitted through you according to your knowledge and all its fallibilities and errors? I have spoken things that were wrong while speaking the Word of God but the Spirit of God still broke forth because the power was the Spirit, not the exactness of what I was speaking. So it is with the bible.
