This is a very difficult question to answer. Some people say that consciousness is being aware of what is going on in our own minds. Some people say that it relates to language – that we need language to have an “internal narrative”, and that without this we are not conscious. It is likely an emergent property of our evolution that came about as our brain power increased and we developed language, memory, and other high-level cognitive functions that enable us to observe events, control our actions, manipulate information and ultimately make sense of what goes on around us. There is no accepted definition of what consciousness is, so nobody can say for sure what brain functions or cognitive abilities are required to say that creature A is conscious and creature B is not conscious, or vice versa.
