Biology...What is life?

So my first Biology class began with the question that everyone has: "What is life?".  We discussed it and it basically boiled down to the fact that living cells determine whether something has life in it or not. Even after something is what we consider dead, there is still life because some of the cells are still living, but will eventually die without the proper nutrients i.e. the basic oxygen. My professor said something very profound to me in my first biology class, he said that everything living, must have ORDER. This got me thinking. If living things must have order then how could we have NOT ben created by a higher power, by a creative being? How could a "big bang" cause order and life? How could that have caused our intricate body systems to begin and keep us alive? The more I study biology or anything about this world it points me more towards knowing and affirming my belief in God.
But this question made me think of an even different question that everyone has which is "What is the MEANING of life?". In different classes that I have taken we have discussed this question and asked ourselves why are we here? How are we here? What caused this place we call the universe come from and why did it happen? These are questions that people have different theories on and ideas about. The reason we were put here on this earth was to glorify God. This is hard to understand but it is why we are here, to bring glory and honor to the King of kings and Lord of lords. All of creation points towards His majesty and awe. Just our bodies being able to function show how great and powerful and creative He is. "He is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together." Col. 1:15-17
