There exists a purpose behind each of the creations.
The purpose of creation is something that puzzles every human being at some point in his or her lifetime. Everybody at some time or another asks themselves the question “Why do I exist?” or “For what purpose am I here on earth?”. The variety and complexity of the intricate systems which constitute the fabric of both human beings and the world in which they exist indicate that there must be a Supreme Being who created them.
Humankind is not, in fact, the greatest creation. Allah says in the Quran: “Indeed, the creation of the heavens and the earth is greater than the creation of mankind, but most of mankind do not realize it.” (Quran 40:57)
