That’s a great question!
What is truth?
Is it a consensus? If we all believe the world is round, does it make it true?
Is it one’s perspective? Are there infinite genders or 2?
Who decides truth?
For me, I believe there is a Creator to our universe. Before time and matter our Creator, the God of the Bible, was. He is, and will be. For all eternity. I believe truth can only be completely understood when knowing that God is source of all Truth. And that there is but 1 God. He created all things. He sent his Son, Christ Jesus, to die for our sins that we may pardoned of our sins and join God in eternity.
Do I completely understand truth because I am a Christian? No. But I believe you those who are not believers in Christ are missing a fundamental truth that shapes your understanding of the universe.
Much like how Bitcoin can shape your understanding of truth in the economy and diseases of fiat.
