I know it sounds crazy, but just think about this: If life on earth arose due to the very slow, very brutal process of natural selection, as the overwhelming majority of scientists—theists and non-theists—believe; a process in which over 99% of all species which have ever existed are now extinct, does that really sound like the handiwork of an omnipotent, omniscient, perfect supernatural being or does it sound like the clumsy, bumbling methodology of a mortal being?
So… what if our universe is the byproduct of an experiment gone awry by a scientist in another universe billions of years ago? That universe having collapsed on itself shortly thereafter, as have the many universes which preceded it. Our universe exploded with a BIG BANG out of the previous universe as a tiny pinpoint particle to become the vast expanse that it is today, after billions of years.
But where did the material involved in the Big Bang come from? And who made that previous universe out of which our universe was born? Who knows! Maybe a supernatural being got it all rolling! However, surely no competent supernatural being would claim responsibility for the disaster that is our world today.
Our Creator must have been a mortal!
