This “first cause” of the universe accounts for the beginning of all space, time and matter. It must, therefore, be non-spatial, atemporal, and immaterial. Even more importantly, the first cause must be uncaused. If this were not true, the cause of the universe would not be the “first” cause at all. Theists and atheists alike are looking for the uncaused first cause of the cosmos in order to avoid the irrational problem of an infinite regress of past causes and effects. It is, therefore, reasonable to accept the existence of an uncaused first cause. — J Warner Wallace (from, Who Created God?)
