Hello,
In the strictest sense I am agnostic. I believe that for someone to be 100% atheist is as unscientific as being 100% theist. Imagine a scale 1 to 7.
1 = I believe 100% God exists
7 = I believe 100% there is no God.
I would place myself a 6.99. Technically this makes me an Agnostic however I identify myself as atheist as I do not believe in a god as much as I believe in fairies or unicorns. They may exist in some far stretches of the universe, however I highly doubt it based on common sense and logic.
God may exist, he may well do, however the bible was a book, a very good one, in the same sense that Harry Potter is a good book. I do not believe Hogwarts is a real school and I do not believe Moses parted the Red Sea.
As for science, I do not need to hold faith or belief. Hard evidence and rigorous testing of theories distinguishes itself from faith.
