Science is very helpful in uncovering some of the questions about our world and in helping us to live healthier lives. However, even what it uncovers is usually based on hypothesis. It can not be taken as absolute truth because it is always changing. It needs to be seen as complementing our world views.
Whether or not Science is good, is another question that is completely based on ones opinion. In my own, yes, I think Science is a good thing and a decent hobby. Science helps expand the mind and helps people understand what they are good and not so good. Not to mention, they can learn new things by studying general Science.
