Everything probably started sometime. When and how? The concept of God might be an explanation, but I will disregard it, not only for it being naïve and fatalistic, but it also just moves the question to "Who created God?". There are physical theories like Big-Bang, strings and multiverse, but they also raise further question, and - frankly - does it really matter if some theory is true or not? If you somehow knew that it's true, would you be in any way in a better position than a Panorpa communis that doesn't know - and doesn't give a shit - about it? After all, if the knowledge is so important, why millions of people sit and meditate, trying to forget everything and ease the mind, with apparently not much success. Look at the Panorpa communis! Its' meditation - the way of life actually - is much more effective.

My Theory of Everything goes like this. In the beginning there was nothingness, consisting of matter and antimatter in equal parts, which nihilated each other. But nothingness was slightly random. At a certain time matter gained a tiny advantage in being more probable. Even a single particle of matter that prevailed over antimatter was able to start its exponential growth, just like the virus epidemic. From then on the evolution took over, evolution from elementary particles to more and more complicated forms. By this reasoning it is not difficult to understand the seemingly unconceivable complexity of organic life, as a product of billions of years of evolution. Human consciousness, so much self-praised, is then no more then a by-product in the evolution of matter. Pondering about the complexity of (human) life is not the way to revelation. It is the opposite: to understand - or rather to identify with - the basic structure (which I call electron) as a building particle of everything.
