This is an interesting point that I don't think anyone has brought up before, but I think that the problem with this is that you're trying to conflate what we are biologically, and who we are individually.
Are you suggesting individuals exist apart from their biology?
A baby is fully developed by 24 weeks, and abortion is illegal by week 24.
Fully developed according to what standard? Their lungs, teeth, taste buds, eyes, hair, fingernails, fat stores and virtually every vital organ are underdeveloped by week 24. Without the assistance of extremely advanced neonatal technology, they would surely die outside of the womb within 24 hours and if they don't die, they are far more likely to experience cognitive and physical developmental issues that otherwise would not have plagued them had they been carried through the full term of their mother's pregnancy.
The question on the table isn't "when does a fetus become a baby?," but "when does a human life begin to exist?" If human life is valuable, what makes a baby more valuable than a fetus if both qualify as human life? Your answer seems to be tied to how many cells the human organism has divided into at some arbitrarily chosen moment in time (24 weeks), as if crossing a certain numerical threshold can somehow add more humanity into a living organism that is already quintessentially human.
What differentiates a non fully formed (by non fully formed I mean they're fully developed in the womb) and a fully formed baby is just that, that one's completely formed and one isn't.
See above.
If we were to say that a non fully formed baby is a potential life and that it should be treated equal as an actual life, then you could say that each individual sperm and egg are a potential life deserving of the chance to live.
Fortunately, this isn't my argument. Rather, my contention is that the moment of conception is the moment a human life is born, not a potential human life,
an actual human life. Individual sperm and eggs cells are missing vital genetic information that distinguishes an individual human being from a mere gamete.
The moment the sperm and egg unite to form a zygote, however, a human life is born with an intricate genetic blueprint laying out a developmental path that extends
far beyond the womb, detailing each biological stepping stone towards adulthood. The context of the environmental or the time elapsed since the person's initial conception is irrelevant to the fact that their humanity has been intact since the beginning and is universally with them through every stage of their development.
This isn't always the case, in some cases condoms break,
Using any type of contraception is always a measured risk, as no method guarantees 100% success. Thus, my statement holds true as they are consenting in full knowledge that their actions
can lead to pregnancy. If this weren't the case, they wouldn't take premeditated measures to decrease the risk.
or they didn't even agree to having sex. I'm referencing when someone forces someone to have sex without permission not saying the actual word since smashboards censors it.
While I agree that this is a categorical exception, it seems somewhat ironic to use it as a defense for abortion. If a woman conceives after being overpowered and violated against her will, unable to defend herself or alter the reality of the violation, is her decision to terminate the life she carries any more ethical when she is violating the will of the child thriving in her womb? In saying, "What I want comes first, no matter the cost, no matter the toll it takes on another human's life" is she not adopting the same philosophy as the person who violated her? Is a human's inability to come to their own defense a genuine criterion for their disqualification as a person and subsequent termination?
It's not just that though. In a lot of cases it leads to people having horrible lives because a lot of people getting abortions are people who can't afford to take care of the baby or don't have a person around to take care of it for them.
According to the nation-wide Finland study I cited earlier, women who had abortions were three times more likely to commit suicide compared to the general population and six times more likely than women who gave birth, so arguing that abortions somehow contribute to a greater quality of life is verifiably false when the freedom promised through the abortion procedure frequently acts as the very snare that exacerbates and ultimately destroys a person's life completely.
As far as economics or other types of hardships are concerned, open adoption is a fantastic option for mothers who know they can't provide the life they want for their child. They not only get to bless a family that likely couldn't have children of their own, but they also get to bless the child itself. By giving up their own pride, vanity, selfish ambitions and even the parental bond itself, they operate according to the highest ethic of love, sacrificing their happiness temporarily so that something greater than themselves would manifest.
So it leads to parents struggling to support their kids, and sometimes unsuccessfully, and it also leads to a lot of people getting on welfare and putting pressure on the government to take of them.
If people are unable to raise their children properly while simultaneously being unwilling to place them into an adoptive family that can provide for basic necessities, the ethical choice is to remain celibate and/or undergo sterilization, not to destroy their offspring to maintain a hedonistic lifestyle free of responsibility.
The reason is that we have autonomy and we can make decisions for ourselves.
We have autonomy by degrees, from conception to death. None of us are ever fully autonomous, none of us ever make decisions in a vacuum outside of external influencing factors. So, even the smallest measure of autonomy or decision making ability is sufficient in distinguishing a clump of cells from a human being. Thus, when a zygote continually demonstrates its will to live by independently (that is, apart from any conscious decision making of the mother or father) replicating, absorbing nutrients and rendering increasingly complex sequences of genetic code into proteins, lipids and other basic building blocks that directly impact its cognitive and physical development, trying to strip it of its autonomy makes no sense.
Does it lack autonomy because it only thrives in a certain context? Don't we all? If I evaporate all of the earth's water or nullify the oxygen production by destroying all photosynthetic organisms, can't the same be said about you and me? Is not the earth merely a large scale womb protecting and nourishing its children? Why then, if we're unwilling to deny our own autonomy despite our immense dependence on our environment, are we willing to deny the autonomy of a child in a parallel situation?
There are also a lot of scientific studies that our conciousness could (partly) be a byproduct of our senses which is where we get this confidence, you can understand you own reasoning you don't just come up with things. This is also where we get secularism and morality on a societal level.
Yes, but our senses are derived from genetic precursors which are derived from chemical precursors which are derived from atomic precursors which are derived from natural laws. The $64,000 question is this: did those natural laws spontaneously emerge from NOTHING, as some seem to suggest, or were they the product of intelligent, conscious, willful effort to create a universe that generated and sustained life?
If we are unable to answer this question with certainty, we have no ground to stand on when we subjectively determine what does and doesn't constitute human life. If we are indeed the product of chance and nothingness, moral relativism is a legitimate worldview and we have nothing to objectively anchor our ethics to, which means trying to answer these questions with a response other than "There is no real moral truth, therefore to each his own" is an exercise in futility. If, however, we are the product of something greater than ourselves, then every single life is a cosmic miracle and we have ZERO authority to decide who lives or dies, let alone what constitutes an ethical decision.
Also, in a lot of religions it is said that God gave us the ability to choose what we become and free-will to think for ourselves.
You cannot invoke God as the source of our existence or consciousness without also invoking him as the source of our morality. If God exists, then only His determination of whether or not abortion is a ethical matters and any attempt to answer this question independent of God's wisdom is obsolete.
