I’m sorry, but that makes no sense to me. Your progression was:
eggs/sperm–>fertilized egg–> embryo–>fetus–>baby–>child–>adult
This progression is completely correct, if the egg and the sperm come together to become fertilized, and nothing stops it (whether it be a natural “death” or deliberate act). If you start with an egg or sperm, which come together through fertilization, you will end up, eventually, with an adult person.
If, on the other hand, you have just an egg, the following will never happen, at least not naturally:
egg–>fertilized egg–> embryo–>fetus–>baby–>child–>adult
An egg is a living cell, as all of our cells are, but it is not a person, and will never develop into one if left on its own. An egg is not a step in becoming a person, the fertilization of it is.

When eggs start spontaneously developing into babies without the benefit of being fertilized, then you will have a valid comparison. That first item in your line is egg/sperm…you could never have the same progression if it was just egg or just sperm. It really ought to be: egg+sperm–>fertilized egg–> embryo–>fetus–>baby–>child–>adult.

The problem with your thinking is that you are selective in what you consider natural and what you do not. You can’t have it all ways at once depending on what suits your argument.
You say that “If you start with an egg or sperm, which come together through fertilization, you will end up, eventually, with an adult person”. Sure you will, if there are a number of inputs along the way. For the fetus to become a child, the parents have to input vast amounts of resources, consciously applied. Those resources are of course applied because parents make a decision they want to apply them. Without those resources, the fetus won’t make it.
But if you are going to allow that as being “just natural” then to be consistent you also have to allow the basic urge for males and females to create fertilised eggs as also “just natural”.
You say “If, on the other hand, you have just an egg, the following will never happen, at least not naturally: egg–>fertilized egg etc” If you have just an egg - in its usual place in a female - the female will behave in ways that will end up with the egg being fertilised. If you have just a newborn baby, she will behave in ways that end up with the newborn becoming a child. If she doesn’t behave in those ways, neither thing will happen.

The whole pro-life debate is shot through with inconsistency and arbitrariness.
