So, in the context of the creation story dictated by the Bible, can you explain to me a) the dinosaurs, b) the iron age, c) the stone age?
Okay... First, just by explaining the confusing part of the creation story, I will answer all three of those questions...
We're going to look at Genesis 1:1, which reads: "In the beginning God created the heavens and the earth." Simple enough right? Where people get confused is the end of verse five where it says: "and there came to be evening and there came to be morning, a first day." The creation account details 6 creative days, with the 7th being declared as a day of rest. But these days were not literal 24 hour periods. Why can I say that? Look at what the Apostle Peter recorded.
"one day is with [God] as a thousand years and a thousand years as one day." that quote coming from 2 Peter 3:8. So basically, the term "day" really has no meaning to God. It is used as a way of dividing up the periods in which God created various aspects of our planet... Answer your question?
