The texts have been entrusted to the same class within the Hebrew culture for thousands of years. As far back as you care to look - checking against every other known copy, you'll find the text consistant. That's not a tough act to follow, it's near impossible considering these folks did it by hand in an unforgiving form on scrollpaper that you just don't get out the white out and correct for errors. How do I know? Simple, the text and it's history speaks for itself. I've gone the extra step and actually bothered reading it and testing God on much of it - panned out well for me. I chose to believe my experiences. Just too many things you can't chalk up to random chance. May be hard for you to understand as you chalk up everything to random chance on evolution with far greater odds than anything I'm aware of against it. But there you have it. My faith is in God, yours is in chance and "millions of years". We both have a religion. The difference is, I don't feel I should have to pay taxes to teach yours in schools while mine is restricted in public - the height of tolerance as it were. If religion has no place in the classroom, evolution don't belong there. It ain't science.
The difference is you believe the earth is 6000 years old.
