Body tattoos have been part of our society since the early days of civilization. Initially people used to have tattoos based on the natural things or the things they could see around them. The tattoos made on the body of the people represented their fear and respect for certain things. Slowly the concept of Gods and supernatural things took place in the tattoo art and people started getting different designs on their bodies. Tattoos are basically the different images and designs people get created on their bodies to introduce themselves to the outer world. During early civilizations, people used to believe very strongly that the world is created by the God only but with the advent of science, the way of thinking in the people have changed. There are many people who believe that there is no existence of god and they base their belief on the Darwin’s theory of Evolution. Atheist tattoos are those which represent that there is no existence of God and the nature has the capability of creating various species through evolution. One very important and well known atheist tattoo is the image of finch birds on the body to represent that there is no God and no religion.
