There are two main theories for the origin of the universe: intelligent design and random chance. Intelligent design proposes that a higher power created the universe, while random chance suggests the universe was created by a random event like the Big Bang. Previously, a third theory that the universe always existed was accepted, but has been disproven by Einstein's theory of gravity and Hubble telescope discoveries. Both main theories have flaws - intelligent design lacks scientific basis, while random chance contradicts established laws of physics. The theories can be summarized as creation occurring as described in Genesis, and random chance proposing the universe was initially compacted matter that exploded in a big bang.
