Accidental Life

Is all life on earth accidental—just happenstance? Well if you buy that then I guess you can tell me where the building blocks of life came from? A big bang? What blew up? I mean, when you have an explosion something blows up. So there had to be something to blow up, if not, then where did the material come from for the big bang to blow up? Was material already there before the big bang and if so where did it come from? If it wasn’t already there then how can you get something from nothing in order to blow up? Only God can make something out of nothing. So God created life and that was certainly no accident.
