Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. 2 Timothy 2:15
"Some say that the days of Genesis 1 can be understood as eons of 
time, but that God
stepped in to do some of the more incredible things at various
times—like making pine trees and people. This so-called ‘progressive
creation’ view has God creating progressively over eons of time.
Others claim that Genesis is a mere literary device, a framework upon
which hangs important theological teaching—like clothes hanging on a
clothesline. They argue that the clothes are the important thing, not
the clothesline, so we should not be worried about trying to connect
Genesis to the history of the world (this is the ‘framework
hypothesis’).
Yet others say God used evolution to make everything (‘theistic
evolution’) and that Genesis has no relevance to understanding the
history of the universe; it is some sort of ‘myth’. Science tells us
when and how the universe came into being; the Bible tells us why. They
are two separate domains of knowledge.
The above views tend to overlap in a fuzzy way in the minds of many who
have not thought logically about the effect of these views on the
Gospel." CMI
