Some say 100,000,000 years old, others (who aren't so bright) say 2003 years old. In my honest opinion (although it looks way to low compared to 100,000,000) the Earth is no older than 20,000 years old. If you count up all of the generations together from Adam to now, it's about 15,000 years. I'm probably wrong, though (as usual). Anyone think otherwise? Thanks for you time.
