Why, the Holy Bible of course. It gives a complete genealogy from Adam and Eve to Jesus. If you add up the numbers given, it's about 4000 years. Add the 2000 or so years since the birth of Jesus, voila: you get 6000 years. As far as any other earth like planets in existence that may have life, well, the bible doesn't mention it, so it can't be possible.
