Incomplete question. I inferred you are referring to the Biblical account of the deluge.
Step-by-step explanation:
It points to what happened thousands of years ago on the Earth specifically in the days of Noah our forefather.
This deluge (great flood) which affected all of humanity is recorded at the Bible book of Genesis 7 and 8 which informs us about Jehovah's (referring to the personal name of the almighty God) decision to destroy all life on the Earth with a flood because of the presence of wickedness all over.
