The Big Bang theory provides the initial framework for understanding the origin of the universe. According to this theory, approximately 13.8 billion years ago, the universe began as an extremely hot and dense point and expanded rapidly, giving rise to matter, energy, space, and time. As the universe cooled, hydrogen and helium atoms formed, eventually leading to the creation of stars and galaxies. Within stars, nuclear fusion produced heavier elements such as carbon, nitrogen, oxygen, and iron, which are essential for life. These elements were later dispersed into space through supernova explosions, enriching the cosmic environment with the
