Prologue
The “kalam cosmological argument” is a popular & powerful argument for the existence of God based on cosmology.
- Everything that begins to exist has a cause
- The universe begins to exist
- Therefore the universe has a cause
Since the universe can’t create itself, it needs a source outside of it, namely a cause that is:
- timeless
- spaceless
- immaterial
- very powerful
- intelligent (to design & fine-tune such a complex universe)
- has a will (abstract entity like numbers can’t cause anything, they only exists)
The best cause for the beginning of the universe would be God.
1) Everything that begins to exist has a cause
We can rationally observe from nature that there’s a pattern of ‘cause‘ and ‘effect‘.
If anything pops out of nowhere, it would sound more like magic.
This premise doesn’t tell that everything has a cause, but that everything that begins to exists has a cause. In the contingency argument, there are things that exists contingently (depending on an external cause) & other necessarily (they have to exists by nature). Our universe could have failed to exists, and yet, does exists. It must therefore have an explanation of its own existence, caused by an external force.
2) The universe begins to exist

We know from the Big Bang that the universe begun to exists billions of years before.
We can know that from 5 lines of evidence (SURGE).
- Second law of thermodynamics
- the universe is running out of energy; if it reach an end, it must have a beginning then
- Universe is expanding
- …
- Radiation after glow
- …
- Galaxy seeds
- …
- Einstein’s theory of general relativity
- time, space & matter are co-dependent for having the beginning of the universe.
Philosophically, an infinite number of regress is also not possible.
In conclusion, the universe has a beginning.
3) Therefore the universe has a cause
The premise 1 & 2 are true, it follows logically that the conclusion is that the universe has a cause.
Since the universe can’t create itself, it needs a source outside of it, namely a cause that is:
- timeless
- spaceless
- immaterial
- very powerful
- intelligent (to design & fine-tune such a complex universe)
- has a will (abstract entity like numbers can’t cause anything, they only exists)
The best cause for the beginning of the universe would be God.
What if…
…the multiverse exists?
It doesn’t change anything: God can still create as many universes as He wants!
…who made God?
Good question, but it’s a wrong deduction
- The argument is ‘whatever BEGINS to exists’
- God is eternal by nature (outside of time)
- Therefore God doesn’t begin to exist in time
…
- The question itself didn’t prevent God from being the creator of the universe
- God is eternal by nature
- If God created the universe & is eternal, then it becomes a circular reasoning
… the universe is eternal?
- SURGE demonstrate that the universe do have a beginning
- Philosophically, an infinite number of regression isn’t possible.
… it’s something else than God?
- It’s possible! This argument was to prove a generic version of God, perfectly applicable to Judaism, Christianity & Islam.
- It still doesn’t disprove that the universe was created by a 1st cause who fits perfectly the description of a Judeo-Christian God.
- Timeless, spaceless, immaterial, very powerful, intelligent & has a will: what else is there besides God?
