Does God Exist? This question often comes into our minds. Let us rationally try to find an answer to this question. My answer to this question is in the affirmative. Based on my study and my experience, I can say with full conviction that God exists. There is no doubt about it. When I say that God exists, I say this in the scientific sense and not in the popular sense. People generally believe that they are in a position to prove or disprove anything. But this is not the scientific position. According to modern science, you cannot prove or disprove anything; you can only arrive at a probability, rather than a certainty. If there is sufficient data to show that this or that thing probably exists, then one can make the statement that this or that thing exists. The present question of whether God exists itself raises another question. Studies in anthropology, that is, the science of man, have established that the concept of God is ingrained in human nature. Belief in God runs in our blood. Every man and woman is a born believer. Especially in times of helplessness and in crisis, we discover that there is a Supreme Being. Every man and woman has experienced this natural fact at least once in his or her life. Then why this question? If the concept of God is present in our flesh and blood, why does one question the existence of God? The reason is very simple. People want to know whether there is a rational basis to their inner belief, whether there is some scientific proof in favour of their inner feelings. I must emphasize that there is certainly a scientific basis for belief in the existence of God. But people generally fail to discover it for the simple reason that they try to apply a criterion that they wrongly believe to be scientific. They want a proof in terms of observation, whereas this is neither the scientific method nor the criterion by which to judge. If you apply the right criterion, you will find that God is a proven fact. Here I recall an incident that took place in 1965, when I was living in Lucknow. I happened to meet a gentleman, who was a Doctor of Philosophy and a great admirer of Bertrand Russell. Of course, he was an atheist. During our conversation about God he asked: “What criterion do you have to prove the existence of God?” I replied: “The same criterion which you have for proving the existence of anything else.” The dialogue ended there. There was no question and no answer after this. Why did this learned man fall silent? The reason is very simple and well known. My answer reminded him of the fact that we are living in a world where inferential argument is as applicable to the concept of God as to any other concept. According to scientific accounts, about 15 billion years ago, at the behest of the Creator, a big cosmic ball came into existence in space. This contained all the particles from which the various parts of our universe have been formed. Again, at the command of God, there was an explosion in this great cosmic ball which scientists refer to as the ‘Big Bang’. After this explosion, all its particles were scattered throughout the vastness of space. Later, according to the Creator’s plan, they began to assemble themselves in different forms. With the coming together of these particles, innumerable stars, galaxies, dark matter, and our solar system were formed. In this way, the entire universe gradually came into existence. The Creator then chose the planet earth for the implementation of one of His special plans. This process spanned aeons, as the planet earth cooled down. By God’s command water was produced and with heavy rainfall, seas and rivers came into existence. About three quarters of the planet earth was covered with water. Subsequently, again according to the Creator’s plan, vegetation appeared on the planet and the land became covered with lush green forests. Then the world of animals came into existence and the earth was filled with all kinds of living creatures: innumerable kinds of small organisms, fishes, birds, four-legged animals, etc. made their appearance. The next stage was to create man and to settle him on the planet Earth. Therefore, the first man Adam and his wife Eve were created. Then human beings continued to multiply until human settlements came into existence in all parts of the world. Later another part of God’s plan unfolded. This was the coming of the prophets to the Earth. All these prophets were human beings. God sent them especially to carry out the task of explaining to human beings His creation plan in a language which they could understand. A whole series of prophets, starting with the first man Adam, continued to come to this world over a long period of time.. Each one came in a different generation -- for instance, Noah, Abraham, Moses, Jesus and the Prophet Muhammad, who was the final prophet. Through the prophets God explained to human beings in one generation after another that the present world had been made as a selection ground: the actual and eternal place for man’s settlement was Paradise; Paradise was eternal as well as ideal in every respect; but entry into paradise would only be on a selective basis. An invisible recording system has been established on a universal scale by God, by means of which the words and deeds of every man and woman are continually being recorded. This record will be placed before them on the Day of Judgement. Then, in accordance with this record of people’s deeds, only those individuals who qualify for it will be selected for this perfect world of paradise. The Creator wanted to grant this special award to those selected individuals, so that they might eternally remain in this ideal world of Paradise, in an atmosphere of all kinds of pleasure and happiness, thus experiencing complete fulfillment. This will be a unique blessing of God which will be bestowed upon only a few fortunate human beings. The rest of the people will be thrown into hell, the dustbin of the universe, there to suffer eternally the torment of deprivation, frustration and despair. The Creator did not want to create this world by a miracle, but rather by cause and effect. The Prophet Moses was God’s messenger. He threw a wooden stick on the ground and by God’s command it turned into a live serpent. Had God so desired, He could have created the entire universe all of a sudden -- miraculously -- like Moses’ rod turning into a serpent.. But in doing so, creativity could not have been developed in man. No science, no civilization would have come into existence. That is why the Creator produced the universe by a long complex process, so that man might develop his thinking capacity and reach a high stage of intellectual development. This was a very lengthy plan, that is why 15 billion years passed in its completion. The present global warming is a warning signal from the Creator that the first stage of creation has come to an end, i.e. the stage of the selection of meritorious individuals. Now the Creator of the universe will uncover the veil of the invisible and appear before us and, with complete justice, will decide the eternal future of all human beings. Now the final hour has come for man to wake up and prepare himself to find a place in the eternal heaven of the next world after doomsday.
