The moment a human egg is fertilized by that one sperm cell a chain of events is set in motion that transforms simple cells into a complex being composed of many different types of cells and structures in a process called differentiation. The newly fertilized human egg becomes a blastocell, a seething super cell of human cells that begin to organize themselves into differing structures that, as they come into contact with each new structure, begin creating new structures in a chain reaction of events that lead to the creation of an embryo and subsequently a complete human being after going through all the evolutionary stages from reptilian to mammalian.
I see the universe coming into existence in a similarly patterned way. Two energy forces coming together that set everything in motion. Everything is as it is because it could not have come into existence any other way. Like a wired program;)
