It isn’t Adam and Eve, it is Noah and Mrs. Noah. All other descendants of Adam & Eve, other than the wives of Noah’s sons, died in the Flood...and ALL of their children were descended from Noah and his wife.
And they came from Adam and Eve.
Except all of Noah’s family were descended from Adam and Eve.
The Bible says that Adam lived to be something like 930 years. And Noah was born another 120 years or something after that. Although take some of that with a grain of salt. IIRC, some of the ages stated may be a bit off due to them rounding off to a “perfect” number which had meaning.
