Establishing Afterlife With Certainty Without A Prophet
Your understanding is correct. The innate feeling of being created and innate sense of morality ( basic good and bad ) do establish the plausibility of one creator. Certain logical testimonies/logical arguments also create the plausibility of ultimate justice that should also happen in some form. None of these are confirmed on the basis of plausibility alone. It is the Prophet who confirms the existence of God, His Attributes, His scheme in this world and the day of judgement.
