You should ask, "Is it likely that natural processes create natural processes?"

Plate tectonics cause earthquakes, solar flares cause weather changes, temperature causes sleet, snow, and water vapor, and so on.

When someone discovers a supernatural process, we'll be sure and revisit the issue.

"A point of creation would be a place where science broke down. One would have to appeal to religion and the hand of God."
-Steven Hawking

Natural – matter, energy, laws of physics, space, time.
Non-natural (supernatural) – not bound by space, time, matter, energy, or the natural laws of physics.

Natural causes cannot ultimately cause natural processes (circulus in probando).
