I know my pastor does not believe in a literal six days, but six ages where God created then let things grow. (He was a geologist before a pastor) He claims the fossil record supports a longer period than 6000 years. He also makes the claim for the hebrew word for day means several things.I disagree.
First, If there are fossils from before the fall, then that would mean there was death before the fall. Romans 5 disputes this along with many other scriptures.
Second, The Sabbath principle, which predates the ten commandments back to creation. In the decalogue, God says "Remember the Sabbath to keep it holy" Exodus 20:11 "For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy."
I find it difficult to believe that the same hebrew word in the same passage means two different periods of time.
Lastly, I do believe in the reliability of certain bible versions over others. I prefer the ESV go to esv.org. I use the NKJV. I will not used a paraphrased version or one that does not translate word for word the original. I also prefer to study the greek original which is more descriptive (tense, action, etc) It clears up a lot of confusion in some passages.
