Evolution and the Cosmos: An Argument Against Deism
The common misconception people have about evolution is that everything we see now is meant to exist. People who don't believe in evolution think all of this "stuff" was intended and nothing but a creator of some kind could make this happen. If one assumes intention, they have already made up their minds that something had to generate the intent, thus deism.
What most people don't understand about evolution is that it is a blind process. It is not guiding itself around, deciding what continues and what does not. We humans and everything we see in nature were not intended to be here. The following statement is the key thing skeptics of evolution must keep in mind: everything in nature is what happened to come out of evolution, we could have just as easily not developed and Earth would contain nothing more than rocks, water, and bacteria. We were not intended to be here, evolution led to our existence, and that's how we are alive, not why we are alive. The word "why" assumes intent, but using "how" let's us more accurately discern our origins without assumption.
Some might say that the cosmos, everything in space, is so magnificent that it could not have happened any other way than with a creator. The beginning of the universe is still being discovered. We know that our universe could have popped into existence out of nothing, as we have seen particles do, thanks to quantum mechanics. Yes, into existence out of absolutely nothing, mind-blowing, but there is evidence to support that explanation. Then we can get into the multiverse theory, that says this universe is just one of a possible infinite number of universes, which is also possible because of the discovery and application of quantum mechanics.
If we are a special creation, what is the explanation for the existence of everything else? Our entire solar system is small compared to the rest of the observable universe. Our solar system exists inside a galaxy, a galaxy in which the distance to its edges is so far we could never reach it. Imagine Earth as a desert planet, nothing but sand on its surface, no water, just a tan ball hanging out in space-this represents our galaxy. Now imagine our entire solar system...our whole solar system would easily fit, with room to spare, in just one grain of sand.
The Milky Way Galaxy is about 100,000 light years in diameter. It is actually relatively small compared to the M87 galaxy which is about 980,000 light years in diameter. And smaller still compared to the Hercules A galaxy which is 1.5 million light years in diameter. So, to reach the edge of the Milky Way, we would have to be in a vessel going 186,000 miles per second (light speed) for 100,000 years, 980,000 years for M87, and 1.5 million years for Hercules A.
These are examples of the vastness of space, but there is more to contemplate. Consider the size of those three galaxies, now think about the fact that there are hundreds of millions of galaxies, that we currently know of, spread out in all directions. Edwin Hubble sparked knowledge about deep space in 1925 when he built his first telescope, and amazing pictures have been taken by the space telescope named in his honor. Each one of those millions of galaxies contains hundreds of billions of stars and planets. What then is the purpose for all of this if it was created? If everything is part of a plan, and we are the creation, why should a god create all of this extra stuff? Once again, we are what happened to come out of our planet's position in the solar system and the random growth that is evolution.
