There is no such thing as random, nor anything superfluos - else the universe would either not exist or become self destroyed. Random itself, or what is percieved to be so, is a subjective view: random is based on a law which allows it to go any way or manifold ways or unpredictably; such an event has to be factored in. This is the higher thought of it. Once, there was no random! We find that both random and predictable occured where once it did not. Here, one must ask - what caused the predictable and the random?
Further, a rock with free shape and form is NOT random. It is the result where wind and water smashes elements in multi directions, each impact predictable if we knew how to measure every single unique impact and its consequences. Every facet of the rock can be reproduced repeatedly in a lab if we could emulate the same conditions. It woud in fact be an anomaly of science if arock was not exactly as a rock.
What we see as random and accidents must be factored in to occur. In the sme vein, the big bang could not go bang if this was not resultant from an intentionally designed set of laws. How so? We have no alternate to it - consider what can cause a bang; a number of factors come into play, primarilly that at one tme nothing we can point to as its cause; whatever we point to never existed at the BB point!
A coconut falling on the head and killing someone is NOT random.
