Atheism is defined as the ‘absence of belief in the existence of god’. This most uncommon notion and belief is usually the outcome of:
Deliberate choice: The person simply chooses to not believe in the existence of a supernatural god. Such a person may blame it on inherited scientific thought and rational thinking. This in turn involves the person attempting to reason with everything and everyone with logic being the base and what meets the eye.
Inherent inability: Sometimes it is observed that certain people find it very difficult to believe in religious teachings because of the very absence of the concept of god all through the growing years.
