The hymns on Creation in Rig Veda refer to several theories pertaining to creation. Several of these hymns regard creation as the result of a cosmic battle, such as those mentioned in the hymns to Indra, God of Rain or as a result of the apparently unmotivated act of separating heaven and earth, an act attributed to several different gods. The hymns on Creation probe the origins of the existence and the creator. On the other hand, certain hymns speculate upon the sacrifice as the origin of the earth and the people in it or upon the origins of the sacrifice. Sacrifice is central to many concepts of creation, particularly to those explicitly linked to sacrificial gods or instruments, but it also appears as a supplement to other forms of creation such as sculpture or anthropomorphic birth.
The hymns on Creation from the Rig Veda narrates that right at the beginning of the creation there was neither existence, non-entity, no world, no sky, no death, no immortality and no day or night. The Creator breathed on His own impulse. Other than Him nothing existed upon this earth. There was darkness too but the entire universe was engulfed in it. All that existed was the formless. But what led to the formation of a `Unit` was the desire to create life force.
The unique feature about these hymns is that they question the very existence of the Creator. According to these the gods came afterwards, with the creation of this universe. In fact when this creation took place or who created it; whether it was created on its own; such questions can only be answered either by the Almighty or perhaps even He does not know.
The theory of Creation discussed in the Rig Veda is partly similar to that explained in Christianity. However its questioning the Creator`s existence or his contribution in shaping the universe puts Rig Veda apart from that of Christian theories.
