I thought it was the inerrant word of God. Now you seem to be reducing it, when convenient, to being men's imperfect memories of their visions, filtered through their understanding at their level of knowledge. Didn't God make sure that they wrote the right thing in His Holy Book?
It is.

No. Not imperfect memories, but descriptions that people would understand. The bible is God's communication to His creation--us. In order for us to understand God, He makes things fairly simple (in relative terms). Thus He showed John what will happen. John wrote what he saw. Just because he experienced a revelation, does not mean he also experienced a magical increase in his vocabulary.

Yup. When Genesis says "day", it means "day." Not some metaphorical eriod of time.
