Think for a moment about what is necessary for a man to survive. Water, the sun, oxygen, the atmosphere, plants and animals… All kinds of details, all kinds of conditions you can or can't think of at that moment are naturally available on the Earth. In addition, when we investigate further, we can see that all these vital needs have a web of interrelated details, and that all these details exist in their full splendor on Earth. Everything on Earth, its living things, plants, the sky, and the seas, all these have been created in the best and most complete way in order to suit the existence and survival of humanity.
Along with the Earth, there are also other planets in our solar system. However, among these planets, the only planet that is suitable for life is Earth. The distance of the Earth from the sun, the rotational speed of the Earth on its axis, the inclination of its axis to its orbit, the structure of the Earth's surface and many other independent factors much like these enable our planet to enjoy a warm temperature which is appropriate for life and to diffuse this warmth all over the Earth in a homogeneous way. The composition of the Earth's atmosphere and the size of the Earth are also just as they should be. The light coming to us from the sun, the water we drink, and the foods we enjoy are extremely suitable for our lives.
In short, any sort of close look at the planet we live on will show us that the Earth was designed especially for man. For us to see that the conditions on Earth were specially designed, it will be enough to take a rough look at conditions on other planets. Take Mars, for example. The atmosphere of Mars is a toxic mixture containing a heavy dose of carbon dioxide. There is no water on the surface of the planet. Huge craters caused by the impact of massive meteors are obvious in the picture on the right. As for the weather, monster storms and sandstorms which last for months on end are quite common. The temperature averages -53oC (-64oF).
Considering these features as a whole, Mars, which among our neighboring planets shares the most in common with the Earth, is clearly a dead planet where life is not possible. This comparison palpably demonstrates that the features which make the Earth a livable place are truly tremendous blessings. The One Who has created the entire universe, formed perfectly its stars, planets, mountains and seas, is Allah. Throughout our lives, we should be thankful for His creations and blessings, and take Him as a friend and protector. Allah, Who is the owner of all these things, is the One Who is worthy of all praise. Allah informs us of this fact in the Qur'an:
Is He Who creates like him who does not create? So will you not pay heed? If you tried to number Allah's blessings, you could never count them. Allah is Ever-Forgiving, Most Merciful. (Surat an-Nahl: 17-18)
