Allah has created us and bestowed upon us with infinite number of favours. If man looks in his own body he will realize the extent of kindness of God. He will find his organs working 24 hours per a day, 7days per a weak without tiredness to keep his life.
God has created this world with astonishing balance in all of its components. This delicate balance prepared the universe to fit the life of the mankind, and this reality implies that man came to this earth to do a mission which is worshipping the creator of this magnificent universe. So let's review how each detail in this universe could affect our existence if it was not at the delicate balance, it exists now.
Take a look around you from where you sit. You will notice that everything in the room is made: the walls, the upholstery, the ceiling, the chair where you sit, the book you hold in your hand, the glass on the table and countless other details. None of them happen to exist in your room of their own accord.
The earth is a living planet where many complex systems run perfectly without stopping at all. When compared to other planets, it is evident that in all its aspects the earth is specially designed for human life. Built on delicate balances, life prevails in every spot of this planet, from the atmosphere to the depths of the earth.
("And if ye would count the favour of Allah ye cannot reckon it. Lo! Allah is indeed Forgiving, Merciful.") (Quran 16:18).
