Hi Daniel. I think you're barking up the wrong tree with the abiogenesis argument there: nobody claims that human reproduction is an example of this (it's life from life, not life from non-life), and if abiogenesis did occur, then that first living organism was very, very different from living humans, who appeared billions of years later.
The abortion part of your argument might stand, depending on whether you've actually seen anyone claim that a foetus is not alive until it is born. I certainly haven't seen anyone claim this. The argument usually runs instead that the sex cells are living cells, but separately are not a human life. Together, post-fertilisation, they are simply a cell, or collection of cells. Nothing 'magic' has happened initiating a spark of life (the cells were, after all, living biological cells to start with). So the question would be, at what point between fertilisation and birth can those cells be said to have become a person?
Unless you're coming from a religious perspective (which I appreciate you are, although that's therefore a faith position rather than one which can be rationally argued), there is no 'magic moment' at which the developing cells achieve personhood. Rather, there is a gradual process of development which is a bit like, say, cooking: there is no point at which the raw chunk of animal you've put in the oven becomes 'dinner', it merely gets more and more like dinner until it is. When it's raw, it's definitely not; when it's cooked, it definitely is. In between, it's a judgment call, involving various factors like temperature, degree of cookedness, levels of harmful bacteria, palatability, and so on.
Same with babies. Fertilised egg ≠ human. Baby at point of birth = human. In between, it's a judgment call, involving various factors such as ability to survive outside the womb unaided, awareness, ability to feel pain, development of other senses, and so on. I think everyone would agree that we should err on the side of caution in terms of deciding whether or not it is ethical to prevent the development of non-baby into baby at any given point, but there is no scientific argument for mooting the issue by pronouncing the fertilised egg to be a human, and announcing that to be that.
Presumably you disagree. If so, maybe you could tell us what magic thing happens at the point at which you consider that the cells become a person?
I have heard it claimed not to be human life to not life period. I also noticed on here a lot of the people who support abiogenesis supports abortion. I know that is a generlization and not all support both.
