The Importance of 6-Day Creation

I'll summarizes some of the main points of the video here.  This is largely a question of if the authority of Scriptures, the reliability of the translation of  Scripture, the infallibility of Scripture (as communicated by God the Holy Spirit to the original authors) and the clarity with which God communicated His message to His intended audience.  I typically follow the Historical-Grammatical approach to Biblical Interpretation (see How to Interpret the Bible which speaks of the various approaches to biblical hermeneutics).  With that in mind, a key verse here would be Exodus 20:11 (the justification for the fourth commandment), "For in six days the Lord made the heavens and the 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."  This leaves no room for Progressive Evolution, The Gap Theory, or any other Theistic Evolution model that tries to insert millions, billions, or even trillions of years into the Bible (what some people call "deep time").

Without the creation account of Genesis 1, the story of Adam and Eve which gives the foundation of law, government, family, and the good work that God calls us to to "keep" (protect and cultivate) His creation don't make sense.  We then also can't explain the existence of sin and death which are explained by Genesis 3, and then the whole gospel falls apart because if there is no First Adam, there is no need for a Second Adam. 

Also, the end of Revelation doesn't make much sense without a literal interpretation of Genesis as the end is a better version of the beginning.  We see the Tree of Life as bookends of the story--Adam and Eve are kept from the Garden so that they might not eat of the Tree of Life after they sinned, but the Tree of Life is available for all to eat freely in the New Heavens and New Earth.  The video makes other good points, but these were a few that I wanted to highlight.
