Are there gaps in the geneologies?

Because so many Christians and Christian leaders have accepted the secular dates for the origin of man and the universe, they must work out ways that such dates can somehow be incorporated into the Bible’s historical account. . . . To fit the idea of billions of years into Scripture, many Christian leaders, since the early 19th century, have reinterpreted the days of creation to mean long ages. Biblical creationist literature has meticulously addressed this topic many times, showing clearly that the word day, as used in Genesis 1 for each of the six days of creation, means an ordinary, approximately 24-hour day.

A straightforward addition of the chronogenealogies yields a date for the beginning near 4000 B.C. Chronologists working from the Bible consistently get 2,000 years between Adam and Abraham. Few would dispute that Abraham lived around 2000 B.C. Many Christian leaders, though, claim there are gaps in the Genesis genealogies. AiG
