In the Bible God says, ‘I…made the earth and created mankind upon it’ (Isaiah 45:12 NIV). Did you know that if the earth was 10 percent larger or 10 percent smaller, life as we know it wouldn’t be possible? Or that we’re just the right distance from the sun so we receive the right amount of heat and light? If we were any farther away we’d freeze, and if we were closer we wouldn’t be able to survive. Consider for a moment the amazing tilt of the axis of the earth. None of the other planets are tilted like ours at 23 degrees. This angle allows the sun’s rays to touch every part of the earth’s surface over the course of a year, as the earth circles the sun. If there was no tilt to the axis, the poles would accumulate enormous masses of ice, and the centre of the earth would become so hot we couldn’t stand it.
