Soul are spiritual; bodies are material. You can touch a body with with a material part of you, but not a soul. The most you can do with a soul is influence it. The soul must have a body to be in the Earth. You created bodies, dear. God created the souls that reside in those bodies.
How is this not self evident?
You are arguing against a fact that is not in dispute.
The problem is not the definition of of bodies or souls - the definition in question is “mother”. What it means to be a mother.
this also falls into the realm of the long ago condemned heresy of nestorianism....

I’ll say it yet again...Elizabeth called Mary “mother of my Lord” - and so do I.
