The question of conscious awareness is a complex and debated topic in philosophy, neuroscience, and psychology. It's important to clarify the terms used in the question to provide an accurate answer.
Conscious awareness refers to the subjective experience of being aware of one's thoughts, feelings, sensations, and the external world. It involves a sense of self-awareness and the ability to perceive and reflect upon one's mental states.
Based on our current understanding, it is generally believed that most adult humans have conscious awareness. That is, they are aware of their own existence and can experience their mental and sensory perceptions consciously. This subjective experience is often referred to as qualia.
However, the degree of conscious awareness can vary among individuals and can also fluctuate based on circumstances. For example, during deep sleep or under the influence of certain substances, conscious awareness may be reduced or altered. Moreover, some medical conditions, such as certain types of brain injuries or disorders, can impact conscious awareness.
The study of consciousness is still an active area of research, and there is much we don't fully comprehend about its nature and how it arises in the brain. As such, it's essential to remain open to new findings and insights as scientific understanding continues to evolve.
