I am bewildered when I hear people say they believe in a supreme God, the creator of all things, because they think the natural world is too complex to be the result of evolution.
Physicists tell us the size of the observable universe is about 46 billion light-years in radius. They estimate there are at least 100 to 200 billion galaxies in our universe, and maybe as many as 500 billion, each with hundreds of billions of stars. And they estimate there are 100 billion habitable Earth-like planets in our galaxy alone. The number of habitable planets in our entire universe is estimated to be 50 sextillion. (I don’t know how many a sextillion is, but it’s a lot.) Furthermore, some scientists have speculated that our universe is just one of a set of parallel universes, collectively called the multiverse.
Considering that the Earth is a tiny part of all of this, I find it very difficult to believe there’s a supreme god who looks, thinks or acts like a male human. For a supreme being to exist it would have to know everything that’s happening all of the time and continuously make an infinite number of simultaneous and interrelated decisions – which would amount to no real decisions at all. It would have to be everywhere all of the time, an integral part of everything and everyone, completely incorporated into all of existence, and couldn’t be a separate consciousness.
People who believe in creationism, also called intelligent design, don’t seem to understand how physics and evolution work. The natural world is a place of constant variation and change. The self-regulating invisible hand of “survival of the fittest” determines which life forms successfully reproduce. The life forms that exist today are the ones that have succeeded. Yes, some species are amazingly unique. But that’s because they had to evolve that way, or they wouldn’t exist.
The process of evolution applies to planetary ecosystems too. Our planet is hospitable to life, but most of the planets in the cosmos aren’t, and there’s no guarantee the environment on Earth will continue to be favorable. Human caused climate change threatens our continued existence, and there’s no god that will fix it for us.
