You see, this is the thing.
Neitzsche once said, "Existence is absurd." Now, I don't pretend to be on the same level of thought as men like Neitzsche or Sartre but I came to this same conclusion myself when I was ten, and sitting in my room thinking. It started with trying to figure out religion, really, and over the years I've expanded it to a lengthy diatribe on why religion and atheism/science are one and the same.
I've been trying to think of a name for it, and the best I've come up with as of yet is "The construction of the self through the deconstruction of reality."
You start with "I." I know that I exist because I am aware that I exist. Cogito Ergo Sum - I think therefore I am. The fact that I am aware, and can question the validity of my existence proves that I indeed exist. All that is around me, this computer, my home, the people I see every day could, for all I know, be false illusions created by my mind to entertain myself and distract me from the fact that I am alone, but I know beyond any doubt that I DO exist, because I can ask the question, "Do I exist?"
I also know that I had an origin. I have a first thought, a first memory, and at some point I took my very first action, meaning that I originated from somewhere before that. The only information I have to go (without creating wild speculation) on are my senses and memories, so from them I can make assumptions as to where I came from.
Logic concludes that I came from Mother. Mother is the first other. My early memory is of her, and from what I've learned in my life I seem to have come from her, and since I know I have an origin, I cannot exist without having come from somewhere, so logic lends it to be true. and now Mother exists. There are two in the universe.
So where did mother come from? Her mother, and her mother and so on and so on, which could go on forever, so we generalize it. Where did "mother" come from? Humanity. Without the existence of humanity, neither mother nor I can exist, and we've proven both to be true, so this means that humanity also has to exist. So we've now proven the existence of the human race.
Where did humanity come from? The Earth. We share chemicals and minerals in our bodies in common with the elements that make up the Earth, so it stands to reason that the Earth is where our bodies - and basically we - came from. How they came to that specific configuration so that we can walk around and move about is a point of oft dispute, but irrelevant to the discussion at hand, so we'll just ignore it.
So where did the Earth come from? The Solar System. We see the sun, feel its heat, and have viewed the other planets and their rotation, and how their movements/alignment affect the Earth's movment, so basically the Earth cannot exist without the Solar system also existing.
Where did the Solar System come from? The Galaxy. We observe it, we study it, in much the same way as the planets in the solar system, so also the stars in the galaxy must exist in order for our own Sun to be allowed to exist and operate in its pattern.
Where did the Galaxy come from? The Universe. However it operates, it's cyclical, like all of the galaxies we can see, and it must exist to contain the existence and movements of all the galaxies, including ours. So we've proven that the universe exists.
So... where did the Universe come from? This is a point of much debate, but for the purposes of time constraints, you can narrow it down to two major factions: Religion or Science. Science believes that the Universe was brought into existence by a random explosion of energy, and most religions believe that the Universe was created by one god or another. Completely different, right? This is where the path diverges into two. So which one do you choose? Take the blue pill, and follow science, or do you take the red pill, and bow to religion?
For the purposes of simplicity, we'll take the path of science first. So, if the universe came from the big bang, where did that come from? An explosion of energy of that magnitude had to come from somewhere, some potential of some kind... so where? There are a lot of theories as to where, my personal favorite being Ekpyrotic, about two cosmic branes colliding every few eons to create a universe, but even if that one - or any of the others - turn out to be provable, then where did they come from? For them to exist they had to have an origin, even if they're nothing more than energy, that energy had to come from some potential... something had to set it in motion at some point. So, what did? And what set that into motion? And what set that into motion?
Now we backtrack, and take the other fork in the road: religion. So if God created the universe, then what created God? He's a being, a consciousness, at some point he had his first thought, took his first action... so from where did he originate? Was he created by an even higher being? Did he coalesce from some pool of chaos that existed before the universe? If so, then where did that pool of metaphysical protoplasm come from? And where did that come from? Etc, etc.
So what you can see is that these two branches of the road, these two hotly debated beliefs about the origins of the Universe, and of existence itself, only diverge for a short time until they finally come back together in one unifying commonality, one concept of origin:
In the beginning there was nothing.
And from that nothing, came something.
Of which all matter, energy, and all of existence was born from.
Existence is absurd.
The fact that we exist, that ANYTHING exists, is paradox.
