The Big Bang theory is supported by several key pieces of scientific evidence, including the observable expansion of the universe, cosmic microwave background radiation, and the abundance of light elements such as hydrogen and helium, predicted through nucleosynthesis models. In contrast, the Steady State theory, which posits a continuous creation of matter, lacks robust observational support and has been largely discredited due to the strong evidence for cosmic microwave background radiation and the discovery of the accelerating expansion of the universe. While both theories attempted to explain the origins and development of the universe, the Big Bang theory remains the more widely accepted framework due to its consistent alignment with empirical data. Overall, the scientific consensus favors the Big Bang due to its comprehensive explanatory power and supporting evidence.
in 3 to 5 sentences evaluate the scientific evidence that supports the big bang theory and the steady state theory.

The Big Bang theory is supported by strong evidence like how galaxies are drifting apart, which suggests the universe is getting bigger. Scientists also found cosmic microwave background radiation, a kind of afterglow from the early universe, and they see that lighter elements like hydrogen and helium are very common, just as the theory predicts. On the other hand, the Steady State theory, which says that the universe never changes and constantly creates new matter, doesn’t have much proof and has fallen out of favor. Because of all this evidence, most scientists believe that the Big Bang theory is the best explanation for how the universe started and evolved.
