AND THEY WERE BLOTTED OUT. Their names were erased from the earth because they left no descendants. [AND NOAH ONLY WAS LEFT.] Only Noah and those with him were left. This verse proves how wrong are some of our ignorant brethren who maintain that the flood did not cover the entire earth.

Bereshit Rabbah 32:10בראשית רבה ל״ב:י׳
“And the water accumulated exceedingly upon the earth, and all the high mountains under the entire heavens were covered” (Genesis 7:19).
“And the water accumulated exceedingly upon the earth” – Rabbi Yonatan was once going up to pray in Jerusalem. He was passing near Palatinos when he saw a certain Samaritan. He [the Samaritan] said to him: ‘Where are you going?’ He said to him: ‘I am going up to Jerusalem to pray.’ He said to him: ‘But is it not preferable for you to pray on this blessed mountain, and not on that mountain of ruins?’ He said to him: ‘In what way is it [Gerizim] blessed?’ [Replied the Samaritan:] ‘In that it was not inundated in the Flood.’ It [a response] escaped Rabbi Yonatan, and he did not answer him at that moment. His donkey driver said to him: ‘Rabbi, allow me and I will answer him.’ He said to him: ‘All right.’ He said to him [the Samaritan]: ‘If it [Gerizim] is one of the highest mountains, is it not written: “All the high mountains…were covered”? And if it is one of the lower ones, the verse does not pay any attention to it and gave it no consideration at all.’ Immediately, Rabbi Yonatan dismounted the donkey and led him on it for three miles [to honor him]. He applied three verses to him: “There will not be an infertile male or a barren female among you, or among your animals [behema]” (Deuteronomy 7:14) – even among the animal drivers [bahamot] among you. “Your temple [rakatekh] is like a pomegranate slice behind your braid” (Song of Songs 4:3) – even the empty ones [reikanin] among you are as full of responses as a pomegranate [is full of seeds]. That is what is written: “Any weapon crafted against you will not succeed, and any tongue that will rise against you in judgment will be condemned. This is the inheritance of the servants of the Lord…” (Isaiah 54:17).
