Here's why:

* Sticks are made of dead plant material. They lack the living cells and genetic information necessary to grow.

* Plants grow from seeds. Seeds contain the embryo of a new plant, along with stored food and a protective coat.

* Soil provides nutrients and support. While soil is essential for plant growth, it cannot magically transform a stick into a plant.

To summarize, a stick is simply a part of a plant that has died. It cannot grow into a new plant because it lacks the necessary living components.
