Understanding the Kalam Cosmological Argument

The Kalam cosmological argument, rooted in ancient philosophy, asserts that everything that begins to exist has a cause. Dr. William Lane Craig explains that this argument originated in early Christian attempts to counter Aristotle’s view of an eternal universe and was later refined in medieval Islamic theology. The argument consists of two main premises: the first states that if the universe began to exist, it must have a cause; the second contends that the universe indeed had a beginning. By referencing scientific evidence, such as findings in contemporary cosmogony and thermodynamics, Craig supports the assertion that the universe is not eternal and thus necessitates a cause.
