God flooded the entire planet...
And all people died except Noah, his, sons and their wives.
Hebrews 11:7 By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith.
1 Peter 3:20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is,
eight souls were saved by water.
Does Scripture require a global Flood?

"Of course, some of the words, such as 'all flesh died' (7:21) might be interpreted as meaning all living things within the local area, as some modern 'scholars' claim. But when a word can have more than one meaning, the context must define its true meaning. And in Genesis 6-10, the context is one of a global Flood! More than 30 times, words and phrases of global scope appear. In each case, the primary meaning is one of totality, but when they are all together, the meaning is crystal clear.
Compare this clear teaching with the teachings of Christ and the New Testament writers, and the conclusion is inescapable. Trying to salvage the local flood idea makes nonsense out of New Testament doctrine.
For example: the local flood theory logically implies that the Indians in North America, the natives in Africa, the Scandinavians, the Chinese, etc., were not affected by the Flood. They escaped God's judgment on sin. If so,
what could Christ possibly have meant when He likened the coming judgment of all men to the judgment of 'all' men (Matthew 24:37-79) in the days of Noah? A partial judgment in Noah's day means a partial judgment to come. Scripture does not stand if the Flood was not global."
