The conclusion that human life begins at sperm-egg fusion is uncontested, objective, based on the universally accepted scientific method of distinguishing different cell types from each other and on ample scientific evidence (thousands of independent, peer-reviewed publications). Moreover, it is entirely independent of any specific ethical, moral, political, or religious view of human life or of human embryos. Indeed, this definition does not directly address the central ethical question surrounding the embryo: What value ought society place on human life at the earliest stages of development? A neutral examination of the evidence merely establishes the onset of a new human life at a scientifically well-defined “moment of conception,” a conclusion that unequivocally indicates that human embryos from the one-cell stage forward are indeed living individuals of the human species; i.e., human beings.
The union of a woman’s ovum and a man’s sperm, unique to them cells, produce another cell called zygote.
Cells are microscopic entities that have a particular function and if joined by others form an organism, like a being, i.e. human.
And that simple definition it defines the miracle that is the zygote! The combination of the unique male and female cells is an independent organism that contains within itself all the necessary components that develop in time an individual until adulthood (post-adolescence).
How that happens, components needed, timing, process, and multiple other enigmas have baffled, up to the present, every scientist and/or mathematician.
Using the simplest definition of “not explicable by natural or scientific law” a zygote is a “miracle”.
Also there is agreement and ample proof that it is an “organism” that defines the beginning of life as acknowledged by every objective medical College as OBs and Pediatrics.
In summary, a union of a male with a female cell forms life. It has to be defined as not explained by human intellect, so it has to be formed by a superior force a “creator”! As every other unexplained event it takes belief in a God to understand what happens.
Unfortunately there are humans that sponsor the ending of this process even though they defend other organisms even as small and uncomplicated as the smelt fish.
The “creator” responsible for life and miracles included in humans a unique combination that is unduplicated (even in twins) and range after their independence and environmental exposure from the Michelangelo, Einstein, Fleming, to a Hitler, Stalin, Castro, to name a few.
The extermination of life at any stage before birth could stop the potential of any other like them and as scientist we define this action as anti-natura and a crime.
