INTRODUCTION:
Science is excellent at answering what and how but why is left to philosophers. I am not a trained philosopher just a normally educated American citizen who sometimes think about things philosophical. Most Americans also think on these things now and again often arriving at a satisfying answer to why. This is my attempt to record my thinking on the various questions and my best common man solutions.
Within the discipline of Metaphysics, the biggest question (tongue in cheek) relates to the origin and nature of the universe. We should settle that before moving down to others. Some of the current theories are:
The Big Bang Theory (most widely accepted) states that the universe burst forth from a blank about 14 billion years ago, then proceeded to expand into a blank and continues to expand today into more blank. The cosmic microwave background provides some evidence for this expansion.
Steady State Theory. This one is difficult to grasp as it seems to present a contradiction in that the universe is said to have no beginning and no end, yet it is expanding and maintaining density.
Ontology (reality, existence and being)
Will Power
How short our lives are compared to the age of the universe.
If time is a thing and the Big Bang occurred, it occurred 13.8 billion years ago.
First life of any kind showed up about 4 billion years ago.
First humanins appeared about 6 million years ago.
Homosapiens evolved about 400,000 years ago.
, the mind (soul)-body question is one of the most intriguing. There are two basic theories, monism and dualism.

Five main branches of philosophy: Metaphysics, Epistemology, Ethics, Aesthetics, Logic.
REALITY
The basic reasoning about what is real turns between illusion and materialism. Subjectivism, Intersubjectivism, Idealism, Phenomenalism, and Solipsism present material objects (matter) as creations of consciousness. In other words, all that appear to be objects are illusions, dependent on being only through the creations of our minds. Under Physicalism all phenomena, mental and otherwise, can be related to the physical; Objectivism defines reality as being composed of all matter separate from consciousness. Physicalism and Objectivism are the theories that are acceptable to most philosophers. Physicalism is a bridge too far. Could there be something more than the physical? In that I am aware that I am aware, I have some feeling of consciousness generated by the brain yet somehow separate. And therein is why Physicalism should be discarded in favor of Objectivism. It is what it is! No word, mental or psychological games. Bertrand Russell in The Problems of Philosophy makes clear that objects, no matter how we perceive them, are real. Our perceptions of matter are as real as the matter, however, bound by the senses. It is this limit to absolute knowledge of objects that opens up certain thinkers to consider matter as illusionary or constructed mentally.
EXISTENCE
Let us dispose of the God issue right off. To believe that some intelligence would create all that is living, an Earth, a galaxy, even a universe for the purpose of our beings is arrogant, selfish, and frankly, absurb. Why? Why would some omni-thing create anything except for its own gratification? And if so, is that how we would like to think of a God? No matter how we look at the existence of anything, we must agree that there had to be something that always was. Our experience of cause and effect and the inability of science to prove otherwise gives us no other options.
How? is not the relevant existence question that keeps one up at night. It's the famous why? question first posed by Guttried Wilhelm Leeibnez in 1697: "Why is there something rather than nothing?" Centuries-long thinking and debating by philosophers and scientists have produced a number of theories. Most of the theories do not appear to be much about the how and why of existence but more about the nature of life. Existentialism-life without meaning, we create meaning, no natural principles ; Ontological Pluralism-there are material objects in reality, there are non-material objects in reality and there could be other qualities of objects in reality; Meinongianism-seems to be very similar to Ontological Pluralism; Universalism-all exists whether physical or abstract; Essentialism-we are the meaning of life by definition; Nihilism-life is purposeless and meaningless; Materialism-all of reality consists of matter; Idealism-the opposite of Materialism, we construct all matter with our minds; Dualism-all is either mind or matter; Phenomenology-a lot like Idealism but with “experiences” added; Monism-defines everything as one thing, either matter, mind (consciousness), or some unspecified substance that combines matter and mind; Absurdism-the condition we find ourselves in, a meaningless, indifferent universe, is absurd, therefore, we make up meaning. Panpsychism-consciousness is universal and pertains to all matter and minds;
TIME AND THE UNIVERSE
A couple of the current theories suggest what is proposed within this writing: that the universe has always been and, if you will, in that sense is god. What comes closest to my thinking are the Block Universe Theory, Static State Theory, and the Cyclic Model of infinite universal expansion and contraction. My theory, to work, must be closely related to a theory of time that purports that all events are occurring simultaneously and forever. Our consciousnesses are mere visitors of a few of the events. Currently, science cannot demonstrate that something can be created from nothing. The scientific principles that champion the creation of something from nothing assume the nothing to be space, a vacuum. Such is not nothing as in some form it contains quantum fields. In the theory of Quantum Fluctuations, we must start with particle-antiparticle pairs. The Heisenberg Uncertainty principle depends on pair of physical properties like energy and time. The Casimir Effect phenomenon are quantum fluctuations. And the Schwinger Effect requires a strong electronic field. If one were to adopt the Block Universe Theory and simultaneity of events, time necessarily becomes null and causality must also be thrown aside simply because without a 'before' any event an 'after' could not have been caused. An expanding universe implies that it is expanding into a space where the universe was not previously. That, of course, cannot be possible. After all, it is the universe and is all.
