The issue is what you define as a basic human right. Here the fight is between the right of a fetus to exist and the right of a woman to control her own body.
The woman was once in the fetal stage of her own life. Wasn't she?
The fact is, She was.
As for your assessment of "the issue?" I obviously disagree with your take on it and here's why.
You (arguably) physically exist as does a child in the womb.
Society does not have the right to take away
your "right to exist." Does it?
Society certainly doesn't have the right to arbitrarily decide
MY "right to exist." Does it yours?
As for the part of your comment about the conflict between the child's "right to exist" and the woman's right to "control her body." I have a question for you, about that.
If a total stranger were to catch you in a moment where you were completely unconscious and they took certain actions that resulted in YOU being connected to their body in such a way that you would die, if the connection is broken before 9 months time. . . . Would you or would you not have an arguably LEGAL right to maintain that physical relationship, until you can be safely separated?
