The document discusses three theories of the origin and existence of the universe: the Big Bang theory, which proposes that all matter originated from a single point that exploded; creationism, which involves a deity creating all matter and life; and the idea that the universe "always has been" and did not have a definite beginning.

1. Alternate theories of the universe

2. The big bang is a theory of how the universe dates back to a point where all matter was condensed into one atom, which exploded and in doing so created time and space.

3. Creationism is a theory that revolves around one intelligent, superhuman creator deity which created all matter and life along with the universe.

4. “ Always has been” is a belief that the universe was not created, but rather has existed eternally and never originated.
