the genealogy

Is unique to the Bible.  Why does it have so many lists of who begat who?  I believe it's because the events described actually happened.  People want to testify that they were there at important events.  The lists of everyone who left Egypt is a perfect example. The book of Numbers contains several lists of genalogies, and it is a record of the wanderings in the wilderness after they left Egypt! When you search "genealogy" you get 50 hits in the NKJV (Gen. 5:1; 6:9; 10:1; 11:10, 27; 25:12, 19; 36:1, 9; Num. 1:20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42; Ruth 4:18; 1 Chr. 1:29; 4:33; 5:1, 7, 17; 7:5, 7, 9, 40; 9:1, 22; 26:31; 2 Chr. 12:15; 31:16–19; Ezra 2:59, 62; 8:1; Neh. 7:5, 64; Matt. 1:1; 1 Tim. 1:4; Titus 3:9; Heb. 7:3, 6)
The grandest genealogy was in Matthew 1:1-18!  Genealogies convey truth!  The truth of God building a relationship with His people! Praise God!
