Eighth Day of Chanukah

“On the seventh day YHWH rested. . . .”

But on Chanukah, the miracle lasted for eight days. It lasted longer than creating the universe and all its inhabitants? Granted, making oil last for eight days seems far less complex than the act of creation. But still, it lasted eight days. A day longer than creation. Does humanity really need such a reminder of the ongoing work of creation?
