Science generally admits that it doesn't know the truth. On some things science feels it is pretty sure, but no one will go so far as to say they've discovered an absolute truth. What science discovers is facts. Science uses these facts to guess at truth. Then they try to disprove their guess by gathering more facts and seeing if their guess holds true.
God is not a scientist. He has no personal use for the scientific method. He knows everything; he understands everything. With this limitless knowledge available, why would we not ask for His input? Why wouldn't we put more stock in His answer than we do in science or opinion? When it comes to truth, there is no greater source.
