What scientists can confirm is that at conception there is a spark of light, not that God creates a new life at conception. I cannot believe or even imagine that when a rapist impregnates a woman, God is standing by and, at the service of the rapist, creates or produces a new life [aside from the ambiguity of "creating a new life", which you should resolve]. Science cannot confirm even the existence of the world it studies...…...
By stating "All of biology starts at the time of fertilization" they are saying life begins at conception.
For more on this, and if you have issue with what these scientists are stating you can take it up with them, you can read these publications and the statements within them,
"A zygote [fertilized egg] is the beginning of a new human being. Human development begins at fertilization, the process during which a male gamete … unites with a female gamete or oocyte … to form a single cell called a zygote. This highly specialized, totipotent cell marks the beginning of each of us as a unique individual."
-Keith L. Moore’s The Developing Human: Clinically Oriented Embryology (7th edition, Philadelphia, PA: Saunders, 2003)
"[The zygote], formed by the union of an oocyte and a sperm, is the beginning of a new human being."
-Before We Are Born: Essentials of Embryology (7th edition, Philadelphia, PA: Saunders, 2008, p. 2)
"Fertilization is an important landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed[.]"
-Human Embryology & Teratology (Ronan R. O’Rahilly, Fabiola Muller [New York: Wiley-Liss, 1996], 5-55)
Development begins with fertilization, the process by which the male gamete, the sperm, and the femal gamete, the oocyte, unite to give rise to a zygote.
-T.W. Sadler, Langman’s Medical Embryology (10th edition, Philadelphia, PA: Lippincott Williams & Wilkins, 2006, p. 11)
"Although life is a continuous process, fertilization … is a critical landmark because, under ordinary circumstances, a new genetically distinct human organism is formed when the chromosomes of the male and female pronuclei blend in the oocyte."
-Ronan O’Rahilly and Fabiola Miller, Human Embryology and Teratology (3rd edition, New York: Wiley-Liss, 2001, p. 8)
"Human embryos begin development following the fusion of definitive male and female gametes during fertilization[.] … This moment of zygote formation may be taken as the beginning or zero time point of embryonic development."
-William J. Larsen, Essentials of Human Embryology (New York: Churchill Livingstone, 1998, pp. 1, 14)
"Almost all higher animals start their lives from a single cell, the fertilized ovum (zygote)[.] … The time of fertilization represents the starting point in the life history, or ontogeny, of the individual."
-Carlson, Bruce M. Patten’s Foundations of Embryology, 6th edition, New York: McGraw-Hill, 1996, p. 3)
Here are some quotes from doctors and scientists,
"It is incorrect to say that biological data cannot be decisive…It is scientifically correct to say that an individual human life begins at conception."
-Dr. Micheline M. Mathews-Roth, Harvard Medical School
"To accept the fact that after fertilization has taken place a new human has come into being is no longer a matter of taste or opinion … it is plain experimental evidence. Each individual has a very neat beginning, at conception."
-Geneticist Dr. Jerome Lejeune
"The exact moment of the beginning of personhood and of the human body is at the moment of conception."
-Dr. McCarthy de Mere, medical doctor and law professor, University of Tennessee
"I am no more prepared to say that these early stages represent an incomplete human being than I would be to say that the child prior to the dramatic effects of puberty … is not a human being. … I have learned from my earliest medical education that human life begins at the time of conception."
-Dr. Alfred Bongiovanni, professor of pediatrics and obstetrics, University of Pennsylvania School of Medicine
"To say that the beginning of human life cannot be determined scientifically is utterly ridiculous."
-Dr. Richard V. Jaynes, obstetrician and gynecologist
"Conception confers life and makes that life one of a kind."
-Dr. Landrum Shettles, sometimes called the “Father of In Vitro Fertilization,”
...and so many many more.
Nor should you, nobody even made that claim. That new life had nothing to do with the actions of the people who procreated other than being the result. And the rapist's intent isn't to create new life, obviously they could not care there is conception or not as a rapist is motivated by a desires of domination and control, impulsivity and disinhibition for gratification, hypermasculine(power), anger, and apathy(sadism).
That's irrelevant and a different topic altogether.
