Here's my take on this: God's existence cannot be prove by science as true or false. Talking about science, we know that if something existed then someone created it , Creator and creation. Enginners created engines, Bakers created cakes/bread, Bees created honey, all things here on earth is based on that logic. So, those who believe in God also states the same, if Life existed then there should be a creator. Now outside of planet earth, the outer space is a vast area that needed an explanation, What does God plan on a very enormous universe? By the way, Big Bang is not the theory of beginnings, but an expansion event. Well, it is also possible na universe really is a thing that existed first without any creator then it is expanding on its own. So in short: hindi ko alam san lulugar, but naniniwala talaga ako na may Diyos, not on a religion-based though.
