When rice cooker was not invented, we just have to cook with fire from burner or from wood. Now we can cook by electricity. Also in the record of the bible in the book of Job in the Old Testament it describes about the water cycle.
Job wrote words that describes the water cycle in his own understanding as it was not yet made known to them yet at that time. When it was discovered it was given the name water cycle.
