you don't have science to support this.
And yes there is "science" showing that life doesn't begin at conception.
Basic 10th grade biology.
There is only one definition of when a distinct (from parents) human being begins. That is at conception.
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.

The French geneticist Jerome L. LeJeune has stated:
“
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. The human nature of the human being from conception to old age is not a metaphysical contention, it is plain experimental evidence.” [The Human Life Bill: Hearings on S. 158 Before the Subcommittee on Separation of Powers of the Senate Judiciary Committee, 97th Congress, 1st Session (1981). See Norman L. Geisler,
Christian Ethics: Options and Issues (Grand Rapids, MI: Baker Books, 1989), p. 149 also Francis J. Beckwith,
Politically Correct Death: Answering the Arguments for Abortion Rights (Grand Rapids, MI: Baker Books, 1993), p. 42.] (Emphases mine – VJT.)
Dr. Hymie Gordon, professor of medical genetics and Mayo Clinic physician stated:
“I think we can now also say that
the question of the beginning of life – when life begins – is no longer a question for theological or philosophical dispute. It is an established scientific fact. Theologians and philosophers may go on to debate the meaning of life or purpose of life, but
it is an established fact that all life, including human life, begins at the moment of conception.” [The Human Life Bill – S. 158, Report 9, see Francis J. Beckwith,
Politically Correct Death: Answering the Arguments for Abortion Rights(Grand Rapids, MI: Baker Books, 1993), p. 42.] (Emphases mine – VJT.)
To cite just a few examples, the
American Heritage Science Dictionary defines “conception” as “the formation of a zygote resulting from the union of a sperm and egg cell; fertilization.” (For reference, a zygote is the first stage of a human embryo.)
Likewise, the entry for “life” in the
American Heritage Dictionary of Science states that life is “the form of existence that organisms like animals and plants have and that inorganic objects or organic dead bodies lack; animate existence, characterized by growth, reproduction, metabolism, and response to stimuli.”
[The] statement that “human life begins at conception” is consistent with both of these definitions, because human zygotes display all four empirical attributes of life:
- Growth – As explained in the textbook Essentials of Human Development: A Life-Span View, “the zygote grows rapidly through cell division.”
- Reproduction – Per Human Sexuality: An Encyclopedia, zygotes sometimes form identical twins, which is an act of “asexual reproduction.” (Also, in this context, the word “reproduction” is more accurately understood as “reproductive potential” instead of “active reproduction.” For example, three-year-old humans are manifestly alive, but they can’t actively reproduce.)
- Metabolism – As detailed in the medical text Human Gametes and Preimplantation Embryos: Assessment and Diagnosis, “At the zygote stage,” the human embryo metabolizes “carboxylic acids pyruvate and lactate as its preferred energy substrates.”
- Response to stimuli – Collins English Dictionarydefines a “stimulus” as “any drug, agent, electrical impulse, or other factor able to cause a response in an organism.” Experiments have shown that zygotes are responsive to such factors. For example, a 2005 paper in the journal Human Reproduction Updatenotes that a compound called platelet-activating factor “acts upon the zygote” by stimulating “metabolism,” “cell-cycle progression,” and “viability.”
Furthermore, the science of embryology has proven that the
genetic composition of humans is formed during fertilization, and as the textbook
Molecular Biology explains, this genetic material is “the very basis of life itself.”
In accord with the facts above, the textbook
Before We Are Born: Essentials of Embryology and Birth Defects directly states: “The zygote and early embryo are living human organisms.” This may be controversial from a political perspective, but the sciences of embryology and genetics leave no doubt as to when human life begins.
