  Solving the puzzle reveals a fully functional, 2500+ year old calendar that is asaccurate as our modern calendar. The extracted calendar is based on a364-day year with a 369-day leap year and a 365-day year that occursonce every 33 years. The average length of a year for this 33-yearcalendar is 365.242424 days which is very near the length of thevernal equinox year of 365.242374 days on which our calendar isbased.
  
  It is now clear that the Bible contains science. It's ancient science, but it's real science.The Bible writers were ancient scientists and the Bible is arepository of their work. If you're a scientist, engineer ortechnician and you've found it impossible to take the Bibleseriously, now you can.
  
  Just as we were unable torecognize this calendar as a calendar, the science of the Bible hasnot been recognized as science because its' authors spoke in parablesand riddles. This was a part of the Biblical culture. The book ofProverbs says that it will teach the reader how to understand the"words of the wise" which consist of proverbs, riddles andfigures (puzzles).
  
  "Besides being wise, the Preacher also taught the people knowledge, weighing and studyingand arranging proverbs with great care." (Ecc 12:9 RSV)
  
  "My mouth shallspeak wisdom; the meditation of my heart shall be understanding. Iwill incline my ear to a proverb; I will solve my riddle to the musicof the lyre. (Psa 49:3-4 RSV)
  
  So when Jesus taughtusing parables and riddles he was following a tradition that wasancient when Solomon was king.
  
  This kind of riddleextends far beyond the genealogy of Genesis 5. Genesis 1 to 11contains a collection of riddles woven into a single fabric. Theriddles continue through the book of Revelation. Once we understandthese riddles we discover that the Bible actually contains aconsistent, workable philosophy that can actually explain the way theworld works.
