When given evidence that refers to the bible, many christians say that they have the wrong interpretation. My belief is that Christians as a whole are twisting the bible's words to fit with our modern knowledge.
For instance, when nonbelievers say that the heavens and the earth could not have been created in a day, some retort that it was not a literal day, that it did not mean 24 hours. I think that thousands of years ago, when we did not have this knowledge, christians would readily believe that it was built in a literal day. Many now say that the bible is not meant to be interpreted literally. Why would God write such a controversial book? If it is not to be taken literally, then what IS god's word?
Almost any prophecy can now be true. All you would have to do is twist the words around. When trying to interpret a prophecy, people tend to make connections to things that may have been purely coincidential. Instead of interpreting a prophecy, you're more like looking for one.
Another thing i have a problem with is how god is holy and almighty, how jesus never sinned, was a perfect son. I personally believe that there is not such thing as perfection, only near perfection. You can find imperfections in everything that is 'perfect'. Even if you do describe something as perfect, it's only in your perspective.
