Nope, it's 100% on target :)

I should add that NO OBJECT/THING/MATERIAL/SUBSTANCE has INTENTION.

Impossible! Nobody can mix chemicals together, and create intentions.
Intentions are the muscle of spirit/awareness, and nothing else.
Nothing at all to do with biology/chemistry/physiology.

Without a spirit, flesh will just rot and decay, and a fertilized egg will not grow, and will be ejected.

Spirit detaches and attaches to flesh/senses every time we go to sleep and wake up, it's nothing out of the ordinary. And it happens at death too.
