If such a source of comets exists, observations are consistent with an old solar system.

About 1950, Jan Ort of the Netherlands postulated a cloud of comets orbiting the sun far outside the planets.

Note that, although observed comet orbits are consistent with such a cloud, there is no direct evidence of its existence: the presence of the comet source is derived from the need for such a source in an old universe.

Second, the distribution of meteors resulting from comets is highly non-uniform around the earth's orbit, while the particles which cause the zodical light must be uniformly distributed.

Lastly, and most importantly, the theory that the particle supply is constantly being replenished must make another assumption: that the rates of supply and of destruction into the sun are roughly equal.

Bales Opening Statement In this argument, I'll stick to the evidence which indicates the earth has a young age.

Any young-earth theory must also explain evidence that seems to indicate that the earth is millions of years old.I do not claim to be an expert in the fields involved. Short-period comets Short period comets disinagrate rather quickly due to interaction with the sun while in the inner portion of the solar system.Several references gave conflicting values, from dozens to hundreds, of the number of orbits to be expected.These methods don't assign an exact age; the rates and initial conditions are not exactly known.However, since the "young" and "old" age ranges differ by 5 1/2 orders of magnitude, it is easy to say which pieces of evidence favor which theory.Also, since there has been controversy on the net, unless otherwise indicated, all references and quotes are taken from works which I have personally examined.
