Yes, the prevailing scientific consensus is that the Big Bang did occur. The Big Bang theory is the prevailing cosmological model that describes the origin and evolution of the universe. It suggests that the universe began as a singularity—a point of infinite density and temperature—and has been expanding ever since. The theory is supported by a wide range of observational evidence, such as the observed redshift of galaxies, the cosmic microwave background radiation, and the abundance of light elements in the universe.
While our understanding of the early moments of the universe is still an active area of research and there are ongoing efforts to refine and improve the Big Bang model, the concept of an initial singularity followed by cosmic expansion is widely accepted within the scientific community.
