The Miracle of Ḥanukkah

If there was enough oil for one night of Ḥanukkah, then why is the first night celebrated? After all, it was going to be lit for one night anyway.

There are two opinions:

The first answer is that the jar of oil was divided by 8, and all 8 lasted for one night each.

The second opinion is more deep. The same jar did last for all 8 days. Nature, itself, is a miracle that Hashem is creating constantly. Even the things that are normal, that we take for granted, a miracle from Hashem.
