It is important to have a critical mind when it comes to science and understand that faith doesn't just reside in religion- atheists and those that claim that science have the answer to everything often truly believe that science is a constant or that it "evolves" as some sort of mystical truth that will lead us to enlightenment, but, practically speaking, science is always incorrect. We don't have all of the answers and we never will. Don't get me wrong- science has made huge advancements in our civilization and almost everything we interact with has been produced in part or has been affected by science, often in a good way but not always. However, science is not and never should be a religion. You can use scientific principles and "facts", but if you call it science, do not be beholden to those "facts".
This does not mean that we should give up exploration or research at all. But by accepting the wonder that is everything we don't and will never completely understand, we are all scientists.
