Conclusion - God is the Ruler of All
The word "coincidence" in explaining a journey thousands of kilometers long towards a specific destination, starting and ending perfectly, is a meaningless one. Natural processes devoid of conscious purpose cannot inform a bird about the duration and direction of a migratory journey and also equip it with the physiological features it requires. There is no scientific evidence or logical reason to make us think so. Defending the so-called evolution of migratory behavior is like asserting that a short-range glider can turn into a plane with Global Positioning System, electronic radar systems and other navigational technology as a result of a series of errors in its radio system.
Giving a little thought to migratory behavior, it can easily be seen that All-Wise and Almighty God directs these living species. That a tiny creature sets out on such a dangerous journey, using the food in its habitat to give it the strength for this journey, employing navigational techniques such as using the Sun and the stars—and most important of all, that in every migratory period, millions of species set off in a programmed fashion—all goes to show that this plan is the work of a Creator.
God has created all species and has inspired in each creature the way in which it should live. As is revealed in a verse of the Qur'an, "Don't they see the birds suspended in mid-air up in the sky? Nothing holds them there except God..." (Surat an-Nahl, 79) the superior skills in living creatures, and the conscious and intelligent behavior they exhibit, show us God's supremacy over animals. God also inspires their migration:
Everyone in the heavens and Earth belongs to Him. All are submissive to Him. (Surat ar-Rum, 26)
People who leave aside their prejudice and think with their conscience understand this truth, that all species come into being with the wish and creation of Almighty God, Lord of the universe. The example of the eel, which travels and knows how to journey thousands of kilometers to the Sargasso Sea to lay its eggs and die, is sufficient proof to inspire faith in the existence of God, because in this behavior, there is judgment, ability and a superior intelligence. It is illogical to think that an eel has such an intelligence that even many humans could not display. God inspires it in them, and those who seek a different explanation cannot find one. In a verse of the Qur'an, God reveals the following:
Say: "Have you thought about your partner deities, those you call upon besides God? Show me what they have created of the earth; or do they have a partnership in the heavens?" Have We given them a Book whose clear signs they follow? No indeed! The wrongdoers promise each other nothing but delusion. (Surah Fatir, 40)
In the Qur'an, God orders humanity to reflect on the creation on Earth and in the skies through the forms of existence He has created. Anyone thinking with his conscience can see evidence of God's existence everywhere. Those who persist in denying such evidence actually do so because of their self-importance. On the subject of such people, God reveals the following in the Qur'an:
Certainly those who argue about the signs of God without any authority having come to them have nothing in their breasts except for pride which they will never be able to vindicate. Therefore seek refuge with God. He is the All-Hearing, the All-Seeing. (Surah Ghafir, 56)
Everything that our Lord has created, from the Earth to the skies, is a wonderful manifestation of His infinite intelligence and incomparable art.
What is in the heavens and in the earth belongs to Allah. We have instructed those given the Book before you and you yourselves, to have taqwa of Allah, but if you are kafir, what is in the heavens and in the earth belongs to Allah. Allah is Rich Beyond Need, Praiseworthy. (Surat an-Nisa, 131)
