Some questions simply can't be answered. Some are physical such as: 'Why did they build Stonehenge?; or 'How do bees manage to fly?' Others are metaphysical such as: 'Why, when we drop a piece of toast, does it always seem to end butter-side down?'; or 'What is the purpose of life?' There is much amusement to be gained from contemplating such matters but probably very little by way of enlightenment. Likewise, the biggest key question in your own personal world right now. Don't strain your brain, just foster your faith.
