The discussion centers on the interpretation of the Big Bang theory, emphasizing that it does not claim to explain the creation of the universe or what existed before the event. Instead, it describes the universe's evolution over time, indicating that as one looks back, the universe becomes increasingly smaller and denser. The Big Bang is characterized more as an observation of the universe's early moments, resembling an explosion, rather than a definitive explanation of its origin. There is no evidence or theoretical framework addressing what caused the Big Bang or what preceded it, highlighting the limitations of the theory in answering these fundamental questions.
