Hmmmm....read the whole thing...
a) no one person wrote the bible, it is a compilation of stories handed down from one generation to another until someone became educated enough to begin writing them down. By that time who know's how far from the original message they were.
b) translators from hundreds of years ago did not fully understand the possibility of one word having more than one meaning in an ancient language. Moder day linguistics have researched and corrected some of these mistakes but mainsteam christians refuse to accept the new translations. I have a "new world translation" from 25 years ago which puts the word era (concept is a "span of time") inplace of the word that was translated as day. the new translation is " In seven Era's god created the heavens and the earth". This alone nullifies the whole creationism vs evolution arguement because there is not set time frame for the "era" when these things occured.
c)to have faith in an intangible being(something you can't see, taste, touch, hear smell, or sense)...is not the same as having faith in the research and proven information associated with most evolutionary studies. A better word in the second situation might be Trust and not faith.
