The cosmological argument is the idea that God's existence can be shown likely by appealing to known facts about how the universe works. The Kalam Cosmological Argument is a variation of that argument. Popularized by William Lane Craig, it addresses the question of the universe's beginning, and its logical cause.
The well-known Kalam Cosmological Argument is sometimes dismissed by skeptics... not on the basis of the argument itself, but because it's used by Christians as support for the biblical account of creation. Here the argument appears in a peer-reviewed scientific journal.
