An observable link between cause and effect does not automatically give the cause independent power to confer existence. Fire affecting wood, a blow affecting glass, or a key turning when a hand moves all show an ordered sequence. Whether the cause creates its effect is a separate question.
Example: Someone turns a key and the lock opens. Hand movement, key rotation, and the opening of the lock occur in order. The chosen hand movement can be attributed to the person, but the sequence does not establish independently creative agency.
The distinction is between observed order and ultimate dependence for existence.
