Science is limited by the progress of knowledge to this point. It is moving that barrier, sometimes two steps forward and one step back. For the most part, I have found science to be honest. At least people are free to challenge it, to expand their learning. The fact that theories are tested, challenged, mocked....then eventually demonstrated or shot down is what is important. The right to question.
Religion can't progress.....it is stuck in old documents that old guys interpret and expect others to trust...."we said so"
