I think I am using "manifestation" in the usual way. Satan "appeared" to be one of the creatures in the Garden. Eve was fooled completely, she did not realize she was being led astray. But the harmless creature was not what it appeared to be, it was Satan in disguise.I do not understand the way that you are using the word "manifestation" in this reply so I do not how to respond to this reply.
Now it might not seem just to hold an animal accountable for an inadvertent action, but for a greater purpose (indicating the value of human life) God does hold animals accountable. If an ox kills a person, the ox is to be killed. Not because it did anything it knew was wrong, but to teach mankind about the value of human life.
Here we have an animal (all of that kind) being held accountable to teach mankind.
