Another good example of memetic viruses are advertisements. Designed and created to spread/infect people and to stick in their minds as long as possible.

There are two types of information, the simple explanation would be truth and lies, truth exists in reality and lies do not. Information which reflects reality is truth, information which does not are lies. True information exists naturally in the universe, there is no false information, that just cannot be. It is only humans who have "created" lying and introduced false information into the world.

If one was to look at this from a religious point of view, truth is god, lies are satan, a concept which everyone is familiar with. So technically we created satan, if you were to view this from such a point.
