Human history, indeed, is the study of how human cultures have grown and evolved and interacted over the centuries. This set of basic ideas is regarded as unquestionably true, and a person can become thoroughly confused and angry when something happens which forces him to question or change these basic beliefs. The basic set of beliefs of a person is that part of his beliefs which he is not easily willing to question. We humans are animals who are also ''meme machines''. The ideas, or ''memes'', communicated between humans, called memes can be regarded as living a life of their own.
Human brains are the most prominent medium in which memes live.
Therefore, all ideas, beliefs and models in any person's brain are memes and are part of human culture. There is no inherent God-given truth in any meme in human culture. God-given'' link with any ''Truth''. Any Truth which a person associates with a given idea is an artefact of this person himself strongly believing things, instead of being a thing directly connected with the idea itself. The idea itself is only a piece of data, like string of letters and digits in a computer program.
