How do we know the pre-existence of Jesus Christ is true?

The pre-existence of Jesus is an essential doctrine of the Christian faith, indicating that He existed with God the Father before all creation. John 1:1 asserts that 'In the beginning was the Word, and the Word was with God, and the Word was God.' This affirms that Jesus, as the Word, is both distinct from and yet fully God. Furthermore, Colossians 1:16 expresses that 'by Him all things were created,' confirming His active role in creation and supporting His divine nature. Such scriptural evidence establishes the truth of His eternal existence.
