The Big Bang theory is supported by several lines of scientific evidence, including the observed redshift of distant galaxies, which indicates that the universe is expanding, and the cosmic microwave background radiation (CMB), which is a remnant heat signature from the early universe. Additionally, the abundance of light elements, such as hydrogen and helium, can be explained by nucleosynthesis processes that occurred just after the Big Bang. In contrast, the steady state theory posits that the universe has no beginning or end and continuously creates new matter to maintain a constant density as it expands; however, it lacks robust observational support and has largely fallen out of favor in the scientific community. Overall, the Big Bang theory is favored due to its comprehensive alignment with multiple observational data, while the steady state theory does not provide compelling evidence to challenge it.
