# Why is there something rather than nothing?

Document: study/why-anything

Creation depends on the self-existent God.

Topic: god
Keywords: cosmological, first cause, contingency, creation, atheism

## Starting answer

<!-- block: answer -->
God gives life and existence to creation while depending on nothing outside himself. Christian reasoning about dependence points toward this self-existent Creator, not toward one more object inside the universe. Scripture identifies the Creator more fully than a philosophical outline can.

Basis: Acts 17:24-28; [R. C. Sproul · Ligonier Ministries — Self-existence and causation](https://learn.ligonier.org/articles/self-existent-god)

## Reasoning 1

<!-- block: reason-1 -->
Created things receive their existence and depend on what they do not supply for themselves.

Basis: Acts 17:24-25

## Reasoning 2

<!-- block: reason-2 -->
An ultimate explanation cannot simply be another being with the same unresolved dependence.

Basis: [R. C. Sproul · Ligonier Ministries — The necessity of self-existent being](https://learn.ligonier.org/articles/self-existent-god)

## Reasoning 3

<!-- block: reason-3 -->
God is underived, not self-created: causing oneself would require already existing.

Basis: [R. C. Sproul · Ligonier Ministries — Self-existence is not self-creation](https://learn.ligonier.org/articles/self-existent-god)

## Conclusion

<!-- block: conclusion -->
The Christian confession is of an eternal Creator who gives existence, not a god who needs to be made.

Basis: Psalms 90:2; [Westminster Assembly · OPC text — 2.1–2](https://opc.org/wcf.html)

## A Catholic contribution, with a defined scope

<!-- block: section-1 -->
Aquinas's arguments from causation and dependence are useful historical contributions. We use Summa I, question 2, article 3 on that specific point, alongside Reformed exposition. This does not adopt his entire theology or settle the doctrines of salvation.

Basis: [Thomas Aquinas · New Advent edition — I, q.2, a.3: second and third ways](https://www.newadvent.org/summa/1002.htm); [R. C. Sproul · Ligonier Ministries — Self-existent being](https://learn.ligonier.org/articles/self-existent-god)

## The Creator is known through his works

<!-- block: section-2 -->
Romans teaches that creation reveals God's power and deity, leaving us accountable. The problem is not merely missing information: sinful people suppress truth. The gospel must therefore address our need for reconciliation as well as our questions.

Basis: Romans 1:18-23

## Objection

Then who created God?

## Reply

<!-- block: reply -->
The claim is not that everything, without exception, has a creator. God is eternal and uncreated. The question challenges the argument only if it shows that this distinction between derived and underived being fails.

Basis: Psalms 90:2; [R. C. Sproul · Ligonier Ministries — Causation and eternal being](https://learn.ligonier.org/articles/self-existent-god)

## Scope and limits

<!-- block: limit -->
A causal argument alone does not teach the Trinity or Christ's saving work. God's general revelation is real, but we need the gospel to know the way of salvation.

Basis: Romans 10:13-17; [Westminster Assembly · OPC text — 1.1](https://opc.org/wcf.html)

## Sources and their limits

### Summa Theologiae I, question 2 [aquinas]

Thomas Aquinas · New Advent edition · Catholic contribution · limited scope

[Read source](https://www.newadvent.org/summa/1002.htm)

Read the objections as well as the replies. Aquinas argues from effects to God; our contingency outline is an introductory reconstruction, not a quotation of his Five Ways. Limited use: causation and dependence in I, q.2, a.3, alongside Sproul. This does not endorse Aquinas's account of justification, merit or ecclesial authority.

### The Self-Existent God [sproul-aseity]

R. C. Sproul · Ligonier Ministries · Reformed exposition

[Read source](https://learn.ligonier.org/articles/self-existent-god)

For God's underived existence and the distinction between being self-existent and causing oneself. This argument does not by itself establish the Trinity or the gospel.

### Westminster Confession of Faith [wcf]

Westminster Assembly · OPC text · Reformed confession

[Read source](https://opc.org/wcf.html)

Our subordinate doctrinal standard for these guides. Citations specify chapter and paragraph. Scripture judges the confession itself (1.10); the confession does not replace Scripture.
