Rain originates from the sun because its heat causes water to evaporate from oceans, rivers and lakes. This water vapour rises, cools and forms clouds. When clouds get heavy, they release rain. So, sunlight starts the process that eventually leads to rainfall.

Class 7 Social Science Textbook Chapter 2 Understanding the Weather Question Answer
Rain is indirectly caused by the sun. The sun’s heat warms water bodies like oceans, rivers and lakes, turning water into vapour through evaporation. This vapour rises into the cooler parts of the atmosphere, condenses into clouds and later falls as rain. Thus, without sunlight, the evaporation-condensation-rainfall cycle wouldn’t occur. This is why ancient texts rightly say “From the sun arises rain.” The sun powers the water cycle, which brings essential rainfall to Earth.
