The Kalam Cosmological Argument, as it is termed today, goes back to the 11th century. Contributors to this argument were Muslim thinkers like Ibn Sina (Avicenna), Nasir al-Din al-Tusi and even al-Ghazzali.

In recent times, the argument has been revived, modernized and strengthened with modern discoveries in physics and cosmology.

The argument goes like this:

1. Whatever begins to exist has a cause
2. The universe began to exist

Therefore

1.  The universe has a cause
2. If the universe as a cause, then that cause is God.

Therefore

1.  God exists
