Everything around us testifies of a God who created all things. The complexity of life points toward an Intelligent Being who designed it, organized it and brought it to existence. The probability that everything around us may have arisen by mere chance is infinitely small, and the idea of a Supreme Creator is the only one that can make sense of all the beauty and complexity of nature including ourselves. And yet, these still do not prove the existence of God in the same sense that scientific concepts are proven. It is really impossible to prove the existence of God in the same, logical way used in science (the scientific method). That is why we say that we believe that there is a God, even if we have not seen him - this is called faith. I have not personally seen God, but my inner self tells me that he exists. Ultimately, it comes down to individual choice. We decide based on what we see and feel, on what the surroundings tell us, whether God exists or not. I choose to believe that there is a God, and this choice is one of my most important freedoms.
