Meteor - Small bodies of matter traveling through space which frequently collide with larger bodies such as moons, planets, etc.
Comet - A celestial body which orbits the sun in large oval paths. It consists of a small dense nucleus (cone) and a "tail" of vapor
Orbits - Circles around
Vaporized - Converted from a solid or liquid into a vapor - a gaseous form
The following are ten observable evidences which testify of a young earth and universe - one which is thousands, rather than millions or billions of years old:
1. Moondust - The moon has no atmosphere. If it existed for millions or billions of years, then tens or hundreds of feet of meteor dust, particles and rocks would have collected upon its surface. However, Apollo astronauts found only one-eighth of an inch (two millimetres) of dust upon the moon's surface.
2. Sun shrink - It is estimated that the sun consumes some 4.2 million tons of matter per second to produce the energy and heat required for life as we know it to exist on earth. In order for the sun to have burned at this rate for billions of years, its original diameter would need to have been larger than the present distance between the earth and the sun. Mercury, Venus, and the Earth all would have been inside the sun!
3. Comets - Each time a comet orbits and passes close to the sun, it is heated. This results in some of its matter being vaporized and lost. This is seen as a hazy or misty tail. Calculations based upon the rate of material loss and maximum possible original size reveal a maximum lifespan of only thousands of years for the most frequently appearing comets.
4. The earth's magnetic field - The magnetic field of the earth is weakening at a measurable rate each year. Projecting this rate backward results in an earth which could not have existed more than several thousand years.
5. The earth's atmosphere - Decaying processes of radioactive elements (such as uranium and radium) form helium. The small amount of helium in the earth's atmosphere reveals a present decay rate on earth of several thousand years. Millions or billions of years of decay would have resulted in much higher levels of helium in our atmosphere today.
6. The earth's surface - Millions of tons of dust from meteors
