Burhan Huduth Al-Ajsam establishes the emergence of all bodies, and forms the basis of our proof for the existence of God. However, an opponent might object to the above by claiming: “the world might be comprised of more than just bodies and accidents, and so Burhan Huduth Al-Ajsam is not necessarily proof for the emergence of the whole world. It therefore, does not suffice as a basis for proving the existence of God.”
We respond: it doesn’t matter whether or not the world is comprised of more than just bodies and accidents, since we do not need to prove that the whole world is emergent in order to prove that God exists. Rather, all one needs is proof for the emergence of anything in the world in order to prove that God exists. And since we proved that something in the world is emergent- namely, the bodies and accidents we observe around us- we can prove that God exists.
The emergence of all bodies necessitates the existence of a being that brought those bodies into existence. Let’s call this being “the creator”, because this being brings things into existence, and this is what “create” means.
The creator that brought those bodies into existence would either be:
- Without beginning
- With beginning (i.e. is emergent)
If the creator is without beginning, then the existence of God is established. This is because a beginningless creator is what we intend when we say “God”.
If we suppose that the creator is emergent, then this creator would itself be contingent upon a second creator to have brought it into existence. This could not have regressed to the past infinitely, as that necessitates the completion of an infinite number of past events. And such a thing is impossible, since an infinity cannot be completed by definition. Therefore, the proposed set of emergent creators would be emergent, necessitating the existence of a beginningless creator who brought this set into existence. And since a beginningless creator is what we intended when we say “God”, God exists.
In both cases God exists. And both cases are collectively exhaustive, so God necessarily exists.
As for proving that the whole world is emergent, then this is the subject of other proofs. For example, Burhan Al-Tamayuz; which proves that God is the only necessary being in existence.
 World: everything that exists except for God.
