Even facts we learned in grade school have changed, (ie-Pluto is a planet, there are only 9 planets, tomato is a vegetable, we are going to the metric system by 1990, etc.)

Once that foundation of facts has been destroyed, then you realize that so much that we have been taught in church is not actually in the Bible, how do you know what to trust? Then you have people that say, well, it is in there, just not in so many words. lol...
