The tree looks guilty.
You believe in an invisible god, and dismiss people who say they are trans? Really?

Termites is possibly the answer. The theory is that they eat plant roots before they can sprout through the desert soil creating a water trap. There is not enough rainfall to create a puddle.

Another group of scientists refute the termite theory.

The tree emits some 'stay back' chemical, the other flora do not?

Similar. Fairy circles are mushrooms, whereas fairy circles are grass.
