As I'm growing up I'm learning more and more about life and our universe a lot of what we learn is of coursed based on experiences. Sometimes when people tell me things I ask myself is that really true?. For example, a friend and I had a discussion earlier about islam and he is muslim and he told me the way the big bang started was predicted when Islam first came out and actually a lot of scientific stuff was predicted in Islam's first stages how can that be possible?. My point is are we suppose to just believe what we are told? How do you regard something as creditable? A lot of the times When I'm learning new knowledge I'm always focusing on the source credibility is that wrong of me to do? I take everything with a grain of salt but if I'm studying biology and is a book by let say Richard Dawkings I would credit the information accurate and not distrust it. Is that wrong? How do you figure out the truth from false knowledge?
