Who am I?

We see ourselves as the top of the food chain on Earth. We do what we want to the other animals of Earth with no consequence. There is no fear of predators or other animals stalking and eating us, excluding perhaps bears or cougars in certain areas. We, as humans, see ourselves as the best possible being, but we are incredibly miniscule in comparison to the world around us. We live in a large world, or at least we see it that way, and yet our world is part of a galaxy that, in comparison, is infinitely diminutive in relation to the universe as a whole. We say that man is grand because of the civilizations we can build and the interactions we make between one another, but with how big the universe is, it is extremely likely that we are not the only ones that can make such connections and have the abilities to build that we do, or perhaps have even better ways of doing these things. In the grand scheme of things, human beings, or even the planet we live on, is nothing. In math, infinity is not inconceivable, it is rather common. There are infinite possible numbers positively and negatively, but that is a very simple example of infinity. From 0 to 1 there are infinitely many numbers, as there are between 1 and 2 and so on. Infinity is everywhere. As there are infinitely many possible numbers, there are theoretically infinitely many planets, solar systems, and galaxies. If the universe is random, it is extremely likely that with that many different possible planets, that one houses a being similar to us. We are as special to the universe as a slab of granite is to us.
Just as we are infinitely small relative to the universe, we too are infinitely large. Our bodies are made up of muscles, tissues, and organs that build up our bodies. These are built up of small organic materials made of up molecules, atoms, etc. As we continue to analyze what we are made up of, we see smaller and smaller components that make us up. In the same way that we believe the universe is infinite, there are also infinitely small parts that make up our anatomy.
As I try to imagine something infinitely small or large, I reach an unsolvable problem. We want to understand what makes up the world around us, but how can we attempt to imagine a infinity of pieces making up an infinity universe? There is a story about a well- scientist (Bertrand Russell) who was describing the orbit of the earth about the sun. After his lecture, an old woman stood up and told Russell he was wrong. That the world is flat and is on the back of a tortoise. The scientist smiled before saying "What is the tortoise standing on?" In this way, the scientist showed that we are never going to be satisfied with an answer to "What makes up our universe?" If we are told the universe is made up of atoms, then we want to make up atoms, if atoms are made up of neutrons, protons, and electrons, then what makes up these? If we continue to ask this question, we reach a point where we are unable to answer it. No matter how hard we try, there is never a definite answer, and yet we continue to search.
I occasionally try to think about what my place is on earth, what it is that I want to do with my life. What will make it worthwhile? But I avoid ever thinking about my place in the universe. I find that you get nowhere. We can use all the technology and knowledge about the universe that we have now, but we will still never understand completely what our place is in our universe or even the importance of our planet. If you want to try and think about makes up our planet, go ahead, but I'm going to stay happily ignorant.
