A human being doesn't come into existence at fertilization, no more does a cookie come into existence when you mix chocolate chips with dough.
You keep saying this, yet it's not making it any more true. Can you find any embryologist, biologist, or scientist in general that agrees with you and cite some research? Because I'm pretty sure you're on an island of one right now with your belief. And I'm pretty sure that you have no education at all in this area by which anyone should be taking you seriously when you are contradicting known science.
“It is the penetration of the ovum by a sperm and the resulting mingling of nuclear material each brings to the union that constitutes the initiation of the life of a new individual.” Clark Edward and Corliss Patten’s Human Embryology, McGraw – Hill Inc., 30
“Thus a new cell is formed from the union of a male and a female gamete. [sperm and egg cells] The cell, referred to as the zygote, contains a new combination of genetic material, resulting in an individual different from either parent and from anyone else in the world.” Sally B Olds, et al., Obstetric Nursing (Menlo Park, California: Addison – Wesley publishing, 1980) P 136
“[All] organisms, however large and complex they might be as full grown, begin life as a single cell. This is true for the human being, for instance, who begins life as a fertilized ovum.”Dr. Morris Krieger “The Human Reproductive System” p 88 (1969) Sterling Pub. Co
When we consider that we are "created in the image of God", God does not physically create anything at conception. Nothing comes into existence. But rather, what already exists, an egg and sperm, simply comes in physical contact with one another (changes form).
Again, this just displays your fundamental ignorance in this subject.
I. 2) Fertilization
Now that we have looked at the formation of the mature
haploid sex gametes, the next important process to consider is fertilization. O�Rahilly defines
fertilization as:
"... the procession of events that begins when a spermatozoon
makes contact with a secondary oocyte or its investments, and ends with the intermingling of maternal and paternal chromosomes at metaphase of the first mitotic division of the
zygote. The zygote is characteristic of the last phase of fertilization and is identified by the first cleavage spindle. It is a unicellular
embryo."9 (Emphasis added.)
The fusion of the sperm (with 23 chromosomes) and the oocyte (with 23 chromosomes) at fertilization results in a live human being, a single-cell human zygote, with 46 chromosomes�the number of chromosomes characteristic of an individual member of the human species. Quoting Moore:
"
Zygote: This cell results from the union of an oocyte and a sperm.
A zygote is the beginning of a new human being (i.e., an embryo). The expression
fertilized ovum refers to a secondary oocyte that is impregnated by a sperm; when fertilization is complete, the oocyte becomes a zygote."10 (Emphasis added.)
This new single-cell human being immediately produces specifically human proteins and enzymes11 (not carrot or frog enzymes and proteins), and genetically directs his/her own growth and development. (In fact, this genetic growth and development has been proven
not to be directed by the mother.)12 Finally, this new human being; the single-cell human zygote; is biologically an
individual, a living organism; an individual member of the human species. Quoting Larsen:
"... [W]e begin our description of the developing human with the formation and differentiation of the male and female sex cells or gametes, which will unite at fertilization to initiate the embryonic development of
a new individual."13 (Emphasis added.)
In sum,
a mature human sperm and a mature human oocyte are products of gametogenesis, each has only 23 chromosomes. They each have only half of the required number of chromosomes for a human being. They cannot singly develop further into human beings. They produce only "gamete" proteins and enzymes. They do not direct their own growth and development. And they are not individuals, i.e., members of the human species. They are only parts, each one a part
of a human being. On the other hand,
a human being is the immediate product of fertilization. As such he/she is a single-cell embryonic zygote, an organism
with 46 chromosomes, the number required of a member of the human species. This human being immediately produces specifically human proteins and enzymes, directs his/her own further growth and development
as human, and is a new, genetically unique, newly existing, live human
individual.
After fertilization the single-cell human embryo doesn't become another
kind of thing. It simply divides and grows bigger and bigger, developing through several stages as an embryo over an 8-week period. Several of these developmental stages of the growing embryo are given special names, e.g., a morula (about 4 days), a blastocyst (5-7 days), a bilaminar (two layer) embryo (during the second week), and a trilaminar (3-layer) embryo (during the third week).14 Dianne N.

All of the qualities described above are observed in every living thing on earth. New and unique cows are born every day. So why is the human embryo more special than any other life at this particular moment of conception?
Again, you seem to not understand basic Biblical teachings on the uniqueness of human beings in the creation order. Humans are a unique creation of God, alone created in His Image. Animals are not. In Genesis, God gave man dominion over animals, and the authority to kill and eat animals.
