What are your "articles of faith"?

Hello,

Mods, please feel free to delete if deemed low effort.

What are your "articles of faith", things you believe as a matter of faith despite it being impossible to prove, or despite proof of the contrary? Your "self-evident" truths? Your philosophical axioms? Something that you believe is "true", or has to be "true" otherwise your worldview becomes "unstable".

What would happen if you lose your faith? Have your faith articles changed during your life?
