What humans really desire in life is comfort and security. This desire comes from the knowledge of being alive in a vast universe and knowing that we only have one life to live in this reality. Although this is a realistic view we constantly question the unknowns in life that reality has to offer.
From within the scientific realm we can see that humans have made truly wonderful discoveries that help to bring us closer to the truth but from the outside science can be thought of as just another belief system with gaps that may make life look hazy and confusing. I myself do not have this opinion but feel that science, and only science, can bring us closer to knowing our reality and the truth about our universe. But, for someone who does not know much about science, such as not knowing the structure and function of DNA, the feeling of knowing their reality comes from somewhere else that is not related to, nor can be compared to, science.
Another belief system exists in our reality which has gained much power from the time it was first conceived, religion. Although it may have been devised as a way of adhering a growing society or reaching out to those in need, its powers today wield a strong influence on the majority of human beings around the world. Many religious belief systems that are based on religion have forced their way into the minds of many and these beliefs have been passed down from generation to generation slowly transforming into beliefs that many have made a part of their biology, such as the soul. Today human beings grow up in societies that teach about the importance of a particular religious belief system to help people believe that there is meaning in life and that our moral compass can be derived from believing in religion. By doing this human beings can more easily believe that their actions in life are governed by a higher power; a power that has all of the answers for life and the universe. By praying to this higher power, God, one can remain close to God and in so doing can find knowledge about their own existence as well as comfort and security that humans long so much for.
The problem with this kind of adherence to a religious belief system is that people are given a false sense of reality. When reality is skewed by merely a religion then the facts of science are broken down into very little pieces and scientific credibility and truth are lost. Since religion offers comfort and security to people through the idea that there is a higher power governing their actions there is little need to believe in something like science that to them seems down right confusing. But, science is not confusing at all. For someone who is seeking comfort and security science offers much more than what a simple religious belief can offer. Science can provide every person on Earth with the knowledge of comfort and security-- one does not have to go as far as praying to God somewhere in the sky for comfort and security but rather can create it themselves from the knowledge of their own lives. For example, if we hold ourselves accountable for our actions we can ensure that the next time around we will perhaps make a better decision and create a more desired outcome. If we constantly seek forgiveness from God we will never blame ourselves for our bad decisions and, in turn, never learn from our mistakes.
We need to devise a set of common values that human beings can follow in order to lead a life of peace, love, happiness, and security. If we can find harmony in life through following a set of sacred values then following a religious belief system will seem unnecessary, almost silly. For those who strongly adhere to a religious belief system, they will need to find 'salvation' by first getting in touch with their biology and family history. Knowing what your strengths and weaknesses are and about your heritage can only set you free from religious belief!
