"Of animal ancestry, man moved ahead as a steward of other creations in taming the environment as they struggle to survive." There are many theories about the origin of life on earth. Many opposing theories and questions have been raised. For example, the Biblical Theory states that a supernatural being created the u- niverse, hence giving life to what was non-existent. The Scientific Theory on the other hand suggests that life was triggered by some force or elements that later led to our existence. The idea carried though by both theories suggests that something was created out of nothing. Why? How? By who? It is still a mystery.
