I too held your belief rather strongly but my view is beginning to change and I found it interesting that a theologian who I respect deeply has changed a lifetime belief concerning the 6 day creation:

A noted evangelical, R C Sproul, has announced a conversion from having previously accepted the theory of evolution as valid science. He now accepts both the Biblical and scientific evidence that the world was created in 6 literal 24-hour days and possibly as recently as around 6,000 years ago.
R C Sproul is the author of some 60 Christian books. He has now stated on the record:
For most of my teaching career, I considered the ‘framework hypothesis’ to be a possibility. But I have now changed my mind. I now hold to a literal six-day creation. Genesis says that God created the universe and everything in it in six twenty-four-hour periods.
The ‘framework hypothesis’ was an attempt to maintain that the Bible was authoritative whilst at the same time denying the six ordinary days of creation. It was first outlined by Arie Noordtzij in 1924. The framework hypothesis holds that Genesis 1 is merely a ‘framework’ into which evolution over hundreds of millions of years can be fitted. Its leading proponents, Meredith Kline and Henri Blocher, have admitted that their adoption of this hypothesis was born of a desperation to fit the Bible into the alleged ‘facts’ of science.
Sounds as if it’s time for Sproul to be put out to pasture.
