No, your definition is a parochially-derived standard definition reflecting the ideas of the definers.
Similarly, I was discussing gun rights with a lawyer. I stated, "I have the right to tuck an Uzi under my jacket and walk through Times Square with it," an assertion that he vigorously disputed. His idea of rights is that rights are whatever the government says they are, an idea that's both hideous and incorrect, but one you can imagine is common among lawyers. He ridiculed me, demanding, "Who knows more about the law, a lawyer who's (insert his achievements, qualifications, tenure, degrees here), or an anonymous guy from the internet?" My response to him applies here: Your "education," from which you're deriving your "facts," is one of parochial indoctrination. Your professors told you what to believe of the law, and you had to adopt those beliefs to get your degree, obtain your law license, and get and retain your job and privilege to practice law in front of a court. It doesn't make you or your professors right; it just makes it the accepted standard.
In this case, those maintaining the accepted standard went through the same process, but the insistence on adhering to the party line is even more ferocious, because society relies on the decriminalization of prenatal infanticide to enable us to fornicate with fewer consequences. Because of this desire, prenatal infanticide will be protected at all costs, even that of defining life without regard for the truth.
That life begins when the spermatazoa breaks the plane can be inferred from scripture. That's more reliable than accepting a malleable definition subject to the parochial indoctrination of fallen man and his rebellious desires.
Why do the heathen rage, and the people imagine a vain thing?
The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying,
Let us break their bands asunder, and cast away their cords from us.
He that sitteth in the heavens shall laugh: the Lord shall have them in derision.
