The philosophy of skepticism rests on the idea that no human experience can tell the difference, for certain, between reality and unreality because of flaws in human perception. If a person sees a ghost, then that ghost is probably not real because of misperception, hallucination, or that person just lied. Science has adopted the philosophy of skepticism and has claimed the right to determine for all people what is most probably real and most probably false through a strict discipline of experimentation and observation. Yet, most scientists ignore the daily, common-sense observation that nonconsciousness always produces absolutely nothing, and they have adopted the metaphysical idea that a nonconscious universe can develop all of the physical laws that govern it and can eventually produce the extremely complex system of life.
But the truth of the matter is that humans never directly experience anything that is not real. Every sense object, idea, feeling, memory, and imagination happens to be real to human consciousness because consciousness makes them real. Consciousness happens to be that very engine of the universe that makes everything that it experiences real. All experiences can only be real because they all happen to be useful to consciousness in some way.
So, is a ghost real? As experienced, a ghost is real because every element of the experience added together that makes up the ghost is always real. Human, shape, misty, and translucent added together make up the ghost and all of these experiences are real. It is only the false combination of these real elements that causes a ghost to be unreal. So how does one know that a ghost is unreal? One can only know that a ghost is unreal because one judges that the false combination of real elements means nothing. That means that the idea of nothing has to be real to consciousness because it is useful to indicate that which is not real. The idea of nothing is itself real. Every element of human experience either means something, or it means nothing, and that makes both ideas real. So where is the unreality of the ghost? It never directly appears to human consciousness. It is covered by the useful idea of nothing.
Every false perception that a human can have always comprises real elements. Most scientists would make the judgment that UFOs are not real, when in actuality, a UFO can be just a false combination of metallic, shiny, disk, and flying; all of which are real with its unreality covered by the idea of nothing. A straight straw may appear bent in a glass of water. But the straw, glass, water, and bent are just false combinations of real experiences, and its falsity means nothing to consciousness. Every mistake that a human can make, and every misperception, hallucination, or even just lies, always comprise real elements in a false combination, and the falsity always only indicates the idea of nothing. Unreality itself never directly appears to human consciousness.
Reality is somewhat similar to mathematics. A person can make a mistake in arithmetic such as 2+3=6, but the 2, the plus, the three, the equal sign, and the six are all real elements of this false combination. When the person realizes that she has made this mistake, she makes the useful judgment that this false combination is useless and means nothing.
All of human history happens to be established on the real fact that all useful combinations of real elements that has been invented or discovered have been retained as being beneficial to humanity, but all combinations that have been proven to be false have been usefully discarded because they mean nothing. In a sense, all false combinations are real because they all can be usefully discarded. All of this speculation completely dismisses the falsity of the philosophy of skepticism. In this regard, scientific inquiry can be helpful, but it has no right to claim dominance over the search for truth.
All of reality rests on the ideas of something and nothing. Unreality covers the unknown and never directly appears to human consciousness. Whatever potential reality lies within the unknown requires human consciousness to extract it from the unknown in order to make it real.
All of this put together means that consciousness happens to be absolutely necessary for the establishment of reality. In the beginning of the universe, an Infinite and Omniscient Consciousness had to be there to establish the reality of the universe.
