I just realized I jumped right into debating instead of answering the OP first. Silly me.
I became a TE because i was never taught everything in the Bible had to be literal. Both my parents are actually Ph.Ds in philosophy, so i had a very strange childhood when it comes to things like critical thinking and religion. (Philosophy of religion is one of their specialties.) I was also a big science kid.
When I first ran into the idea, I, being a child at the time, asked my parents. This is what they replied, broken down of course.
1. Nowhere does the Bible say it must be taken literally.
2. Nowhere does the Bible say it was given word for word and must be historically true.
3. God created the earth JUST AS MUCH as God inspired the Bible.
4. Therefore the earth is the Work of God just as much as the Bible is the Word of God.
5. Therefore God's Work and God's Word will line up.
6. Therefore if an interpretation of God's Word contradicts God's Work, that interpretation must be wrong.
(I was fairly good at basic logic at like 8, and they broke that down to basic if-then statements for me.)
It just seems to be a lot of YECs tend to forget 3 and 4. God created the heavens and the earth. Denying what is evident in them is disrespectful to God. After all, He created it for us, didn't He? It doesn't matter HOW He did it, Genesis 1:1. He did it.
