Because an individual organism's life doesn't "begin". It was created from living gametes created by living progenitors, and at no stage was it "not alive", such that life could begin.
What we call a "person" is not an independently unique strand of DNA. That's a nonsensical measure.
1> It means miscarriages are potential homicides. I've pointed out how silly that is before.
2> It means identical twins are the same "person", because they share the same DNA, and that's how you're determining whether a single entity exists. They cannot be considered separate entities, by your argument, because their DNA is the same.
Yes, the existence of an individual sentient being is what we're talking about.
And that's personhood. Not "life". It's an entirely appropriate point to bring up, because the idea that "life begins at conception" is a religious argument, not a biological one. Biologically speaking, it's just wrong.
