Philosophical argument for the contingency of the universe:
(1) If the universe didn't have a beginning, the universe is eternal.
(2) If the universe is eternal, the past is infinite.
(3) If the past is infinite, there has been an endless amount of past events.
(4) If the amount of past events is infinite, it would take an infinite amount of events to reach the present events.
(5) However, present events are constantly reached.
(6) Therefore, (4) is false.
(7) Therefore, the amount of past events is finite.
(8) Therefore, past is finite.
(9) Therefore, the universe is not eternal.
(10) Therefore, the universe began to exist.
(11) Therefore, the universe has a cause.
