What is the event that the moon looks like a curved boat on July 15?

Please answer clearly first: it is an impossible event.

Explain the reason:

? Inevitable events, when repeated experiments are carried out under certain conditions, some events will inevitably occur in each experiment. This kind of event is called inevitable event, referred to as inevitable event for short, and impossible event is collectively called definite event. The probability of its occurrence is 1, but the event with the probability of 1 is not necessarily an inevitable event. Random events:

1, just crossed the road and ran into a red light.

It will rain tomorrow.

Impossible events:

1, the cork sank to the bottom.

The sun will rise in the west tomorrow.

Inevitable events:

1, the sun rises in the east every day.

2. Throw a square dice and you will get no less than 1 point.

The earth moves around the sun.

The moon goes around the earth.
