When you look up at the sky in the night, you see constellations. Constellations are human inventions, an attempt to ascribe pattern to a random gathering of stars. Why do we do that? The human brain is tuned to find patterns, it is not tuned to understand the concept of randomness. When you find something which is completely random, you still try to find patterns therein. This is because randomness as a concept is extremely hard to grasp. How can you describe randomness? There is absolutely no model through which you might be able to understand randomness. It is therefore impossible to understand.
