A friend says he traveled abroad and learned that after the flood there were other survivors besides Noah and his family. They have a track of these descendants and also possess their historical records. Can you elaborate on this?
While there are some who claim that other people, in addition to Noah and his family, survived the flood, this is contrary to what God has told us. It must be noted that their source for this information is not the Word of God, but man's writings based on man's wisdom and words. Whenever man thinks, reasons and writes from his own understanding, there will be error -- often unintentional, but in some cases with intent to deceive. There are those who desire to disprove God’s Word and there are those who desire to rely on their own understanding to formulate a new insight (not revealed by God) in the Bible.
None of us were present at the time of the flood, and if we had been we would have perished since only eight survived (sorry, I couldn't resist repeating God's words, which I believe are true).
God, however, was there. He's the Alpha and the Omega, the beginning and the end. He has always existed and He is omnipresent (always present), omniscient (all knowing) and omnipotent (all powerful). His Word has been studied by people throughout the centuries and found to be true and trustworthy. So when God said only eight people went onto the ark, along with the animals, we can believe His Word:
"In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark; They, and every beast after his kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort." (Genesis 7:13-14)
Peter confirmed those aboard the ark in his epistles:
"...in the days of Noah, while the ark was a preparing wherein few, that is, eight souls were saved by water." (1 Peter 3:20)
"And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly." (2 Peter 2:5)
"Noah the eighth person" couldn't be clearer. Those on the ark included Noah's wife (1), his three sons (3), their wives (3) and Noah (the eighth person).
