It is surprising how misunderstood atheists are. Most people really do not know why atheists become atheists. There are popular misconceptions such as atheists do not believe in God because they think that something that cannot be seen cannot be believed. Another misconception is that atheists are messengers of evil or the devil. Yet another misconception is that atheists believe in evolution which states humans came from monkeys. All of these arguments against atheism are ignorant and straw-man to say the least.
There is a popular Malayalam film named Kilichundan Mampazham. In that Mohanlal talks about belief. He says that just because one has not seen Dubai, doesn’t mean Dubai doesn’t exist. So far two close friends of mine have used the same logic to me while talking about atheism. They say that if I haven’t seen God, it doesn’t mean God doesn’t exist. Well, first of all I must tell everyone that it is not because we can’t see God that we don’t believe in God’s existence. This argument stems from the lack of understanding of what evidence means. People are yet not clear with the concepts of direct and indirect evidence.
I have not seen my brain yet. In fact most humans have not seen their own brain. However, we know that it exists. We are aware of its existence from various indirect evidences that we can verify. For instance, we can perform an EEG or a PET scan and verify that we have a brain. Other indirect evidences would be the cognitive processes that goes on inside our head all the time. We think therefore, we do have a brain. We really don’t need to cut open the head to verify its existence but if we do, we can be sure that will see our brain. When a crime happens, the detective doesn’t see the crime directly in most cases. He collects evidences such as fingerprints, footprints, blood samples, video and audio recordings, letters and emails, chat scripts, witness testimonies and many other things before drawing his conclusions as to who might be the culprit.
Similarly, we know that Dubai exists from a variety of indirect evidences such as personal descriptions of people who visited that place, photographs and documentaries and news related to that place among others. All these convince us that Dubai exists even though we haven’t visited it. Hence the argument that atheists reject God because they haven’t seen God is meaningless. It is not just the direct evidence that we verify but also indirect evidence. There hasn’t been any testable way to prove that God exists both directly or indirectly. Which is one of the main reasons why we don’t believe in a God.
Carl Sagan once said, “Absence of evidence is not evidence of absence“. However, we must use that statement carefully in any context. Or rather, we shouldn’t misuse that statement. When I speak about aliens, some people ask me how am I so sure about their existence. Of course I am not fully sure about their existence. However, the indirect evidence is so overwhelming. At the time I am writing this, scientists have discovered over 700 planets and over two dozen of them are in the habitable zone around their parent stars, which means they can harbor life as we know it.
Now, life as we know it alludes to the carbon based life form. Carbon as you might have studied in high school, has a property called catenation. It can form long chains of molecules that form “backbone” for other molecules and atoms to attach. Our DNA is one such molecule which can self replicate and therefore form the base for life to evolve. DNA may not be the base for life in other planets but still it is highly likely that it will be a carbon based self replicating molecule. When scientists search for life in other planets, they look for signatures of life such as oxygen-carbon dioxide cycle, presence of organic molecules, presence of moisture in the atmosphere etc. And intelligent or industrialized life form would have further signatures such industrial waste gases, radiation, presence of radio waves artificial light sources etc. These are prominent indirect evidences that scientists are looking for all the time in the planets that are being discovered.
We haven’t found direct evidence for aliens because we have barely started looking. It’s been just over 110 years since we invented radio. Which means, the farthest those early signals have gone is 110 light years. Our galaxy is over 100,000 light years across and have an estimated 400 billion stars. And there are roughly a hundred billion such galaxies in the observable universe (give or take a few billion). In the last 20 years since the first discovery of an exoplanet, we have found over 700 confirmed planets. Hence, the discovery rate is quite high and in the coming years, the number of planets we find will be truly mind blowing. Thus, the day is not far before we find the first clues for a life form that is truly alien. And when that happens, our civilization will be changed forever.
Coming back to the main topic of discussion, evidence can be direct or indirect. In science, a theory can be verified through experiment, through observation or through mathematics. In addition, there is a rigorous process of peer-review. It is only when such a verification occurs that a theory gets accepted in the scientific community. Scientific community is hence very rigid because there is no room for error there. Therefore, any Tom, Dick and Harry cannot come up with a theory and say, “Hey, this is my new theory, accept it.”
God, is a concept invented at a time when there wasn’t an understanding about what was going on in the world. To be more specific, the God in our culture(s) is basically the “God of the gaps”. People tried to plug in the various holes in their knowledge about the world using God(s). Religion was a political and cultural construct invented in order to keep people in control by exploiting this ignorance. However, today we know so much about the world around us that we can start pulling out the plugs from many such holes and put our scientific understanding in place. For example, we didn’t know how things fall in the past, but we do today. So, we pulled out the corresponding plug and put theory of gravity in. We didn’t know why there was a retrograde motion for Mars and other planets, but we do today. So, we pulled out the plug and put Heliocentric theory in. We didn’t know why diseases occur, but we do today. So, we pulled out the plug and put germ theory in. So as and when we learn a new thing about this world, one God disappears or as astrophysicist Neil deGrasse Tyson put it, “God is an ever-receding pocket of scientific ignorance that’s getting smaller and smaller and smaller as time goes on.“
This was a simple article about the atheistic viewpoint. If this doesn’t provoke thought in a religious person and helps him understand why atheist reject God, then I am not sure what will. Any questions on the content of this post is welcome. Thanks for your time.
