The body is whatever contains the human being. A new human being comes into existence at fertilization. We know this scientifically. We know at conception a new, unique individual with its own unique DNA exists.
So worried about me all the time, pretending to be concerned that I am "all alone."
Anyway, it appears you have noticed that human beings having to have a real human being
body is not going to further your mistaken viewpoint, so have reverted to
no real body being required and "human being" needing only to be defined by DNA. As though a blueprint is all one needs for there to be a house.
(By "no real body" I mean having
no substance, a mere invisible single cell will do
without even a hit of flesh and blood.)
One should eventually become aware that merely repeating "a new unique individual comes into existence at fertilization," is no argument at all, as though being fertilized is all that is required for a plant to be a plant. (Doing a little takeoff for humor sake.) And your old standby which it really nothing, "We know this scientifically," when the "science" you present is merely someone else, a professor or something like that, ALSO MERELY SAYING, "human beings begin at conception."
Where you are able to go astray, for of course it is the most deliberate backtracking that is engaged in here, is the "pro-lifer" can neatly substitute "individual" for "human being," and only a bit later without any sort of argument convert that to "human being."
The zygote, the fertilized human egg, is of course something rather than nothing. One could call it "X," if one did not need to
predetermine that it is a human being. "An individual" sounds so much like what any real person is, so
the confusion can be introduced at the beginning.
In other words, one thing I am claiming is that to refer to it as "an individual" is pretty much to
beg the question. Suppose we call it "X," refraining from introducing anything of the conclusion into our premises. What is it? Well one thing we could notice, if we cared for truth, is that initially it is not even visible to the naked eye, about the furthest thing from a human being that it is possible for something alive to be. Like a single protozoa or actual one-celled animal, quite other than the ultimate of God's creation.
Then we could investigate what a human
being actually is, that it has
a human being body, for instance. But the realization it would then have to have at least some flesh an blood means that would never do for the ardent "pro-lifer," so would have to be dropped, ignored, and the strict rules of being sure to NOT pursue the truth, prevail.
The first little paragraph here neatly illustrates the circular reasoning involved. If a body is required, then one says, "whatever there is in a womb or definitely on it's way there is a "body" that "contains a human being." And then identifying it as "a individual" with unique DNA of course proves it. Whereas it only proves that defining things like "body" and "individual" any way one wants to is all that is required to "SHOW" (to the satisfaction of the "pro-life" inclined), that indeed any womb contents is a human being.
