When Atheists are challenged by Christians they are often asked where did the energies and the particles come from? Did they just appear? Atheists come back with the counter question of where did the Christians creator God come from? Did he just appear? That is the mystery of life and the Atheists believe that everything began with science and everything can be explained through science, which is why Atheists believe in the Big Bang Theory. On the other side of the argument , the Christians believe in a God and that this is a higher power that created the universe, planets, moons, stars, and humans who live in this massive universe.
