As comets pass near the Sun, some of their mass vaporizes, producing a long tail and other debris (a). Comets also fragment frequently or crash into the Sun (b) or planets. Typical comets should disintegrate after several hundred orbits. For many comets this is less than 10,000 years. There is no evidence for a distant shell of cometary material surrounding the solar system, and there is no known way to add comets to the solar system at rates that even remotely balance their destruction. Actually, the gravity of planets tends to expel comets from the solar system rather than capture them (c). So, comets and the solar system appear to be less than 10,000 years old.

However, Sagan and Druyan believed that the Oort cloud exists, and went on to predict (p. 211) that “with the refinement of our scientific instruments, and the development of space missions to go far beyond Pluto,” the cloud will be seen, measured, and studied.

If comet formation accompanies star formation, as evolutionists claim, then many comets should have been expelled from other stars. Some expelled comets should have passed through our solar system in recent years. No incoming comet has ever been observed with an interstellar (i.e. hyperbolic) orbit. [See Wetherill, p. 470.]
For the last 150 years, the age of the Earth, as assumed by evolutionists, has been doubling at roughly a rate of once every 15 years. In fact, since 1900 this age has multiplied by a factor of 100!
Actually, most dating techniques indicate that the Earth and solar system are young—possibly less than 10,000 years old.
