A creed is a formal statement of beliefs lies shared by a religious community, which includes belief in ghosts, spirits, or zombies.
The Nicene Creed concludes with the following passage:
We look for the resurrection of the dead, and the life of the world to come.
Upon death, the human body gradually decomposes as follows:
Day 1 to 2 – Body temperature drops; muscular tissues become rigid.
Day 1 to 2 – Small carrion insects join in, looking to feast upon flesh.
Day 2 to 4 – Cell structure begins decaying; stomach bacteria proliferate.
Day 2 to 4 – Maggots and gas rupture the skin, starting a rapid decay cycle.
While alive, the heart circulates blood. The blood grabs oxygen from the lungs and nutrients from the stomach then distributes those items to other organs, which prevent decay from starting.
Humans replenish stomach nutrients by eating plants (that absorb energetic sunlight). Once decomposition starts, reversal (resurrection) is only possible by adding energy to fix problems caused by decay and death. Of the following ideas regarding rebooting an inanimate corpse, consider what is more likely:
Divine resurrection never happened: the creed is unfounded.
