Science and religion seem to be antagonistic to each other. But intrinsically, then- purpose is the same that is, to make life happy and worth living. Both claim to be based on truth, though their methods are different. There are many similarities and dissimilarities between science and religion. The basis of science in earliest stages at least, is believed to have been observation and experience, and it is quite understandable that man must have been observing the natural phenomena and having some experiences of varied type. Yet religion is believed to be much older than science. It is because religion is primarily based on belief and faith which later took the shape of magic. But science in its tangible form came to be recognized much later. It is now almost established that man has evolved from other species after the passage of numerous millenniums. As he appeared on the earth in the present human form, he was awed to watch the lightning in the sky followed by a loud thunder. As he moved on the earth, he came across or experienced floods and forest fire which made him realize the presence of some spirit behind all such things and happenings. He began to feel and realize and associate his own life and fate in the hands of some invisible power that perhaps he gave the name of God. The fact that the name of God in different vernaculars, languages and dialects exists almost; all over the world in all religions, among all races and countries, means that either all mankind was thinking alike at one or the other time or the people in different regions or areas of the world were having some communication system even unconsciously, may be in the form of conveying of some fact, information, secret or piece of knowledge from person to person through the mouth, as the writing process, as we know now, came much later, indeed, recently only.
