Thomas Aquinas, on Job 38:26

“That it should rain on the earth without man in the wilderness, where no mortal dwelleth:”

“He adds the reason why the winds set in motion the rain and the clouds when he says, "to rain on the land of an uninhabited desert," which cannot be lived in because of the aridity of the earth. Vapors bearing rain arise especially from humid places, and so if the clouds and rains were not set in motion by the winds it would follow that it would never rain in dry places. It happens that some places are sometimes irrigated by human industry, when the rains cease. But this cannot happen there, and so he says, "where no mortal man lingers." So human technology cannot provide water for that land.”
