Just curious, about leaving food and water in the desert. Is everything in sealed containers, to prevent evaporation and spoilage? How do illegals know to look for food and water?
And is the food culturally appropriate to the cultures of the aliens?
Bean Taco’s with heavy dose of hot peppers are appropriate food for south of the border folks, and those can last a week without refrigeration.
As for water, sealed bottled water does not evaporate quickly...good for a month.
