Why are there natural phenomena (such as night and day, the sun and the moon, crescents, earthquakes, volcanoes, solar and lunar eclipses, and water) on other planets devoid of life, given that Allah Almighty created them for humans on Earth for specific purposes mentioned in the Quran?

The verse cited by the questioner does not indicate that the subjugation of night and day is exclusively for humans. Rather, it signifies benefit for them, alongside other purposes and wisdoms. The East and West encompass every planet and celestial body, not just Earth. The Quran mentions "the Easts and the Wests" in various forms to reveal astronomical facts that have only recently been understood. Therefore, the questioner's assertion that the crescent moons were created solely for humans, or that the wisdom behind natural phenomena is limited to frightening people, is incorrect. Allah creates what we do not know, and His wisdom is not limited to what we have perceived. Consequently, the questioner's claim that space agencies are being disbelieved with the aim of combating Islam is erroneous and exaggerated.
