That’s a pretty good disagreement, by the way. I’m aware of all this but my context was based on the presumed assumption that the frequency of meteors is increasing long-term. For that to occur there would need to be more meteors everywhere in the inner solar system, not just in the vicinity of Earth. I’m sure you can agree with that.

“That’s a pretty good disagreement, by the way. I’m aware of all this but my context was based on the presumed assumption that the frequency of meteors is increasing long-term.”

The evidence tends to indicate that is a subjective and a false assumption. If by long term you mean the long term experience of the Solar System, then the assumption must be in gross error, because we have obvious evidence that there has been no reoccurrence of the Late Heavy Bombardment in the Solar System. Secondly, the existence of the inner planets of the Solar System make it self-evident that their coming into existence increasingly thinned out the population of matter within their gravitational influences over time. This decrease in the frequency of bombardments overall is corroborated by the ages, sizes, and frequencies of crater formation on the bodies with little or no atmosphere or plate tectonics.

In the case of shorter time periods measured in decades, centuries, millenia, and millions of years, any presently undetermined variations in bombardment frequencies can be attributed to disruptions of the Oort Cloud by stars passing close by the Solar System, collisions in the Oort Cloud and the Asteroid Belt, and perhaps encounters with interstellar debris fields. In each case, the variations in meteor populations would still be governed by non-uniform distributions resulting from natural forces.

Within the period of human history, there is no evidence that one period of time experienced a greater frequency of bombardment oveerall than another period, but it can be inferred there likely should have been due to encounters with meteor showers as a consequence of coincidence with the orbital paths of comets and asteroids.

In the last hald century, the counts of crater formation on Luna and Mars doees not indicate any significant changes in bombardemnt frequencies.

“For that to occur there would need to be more meteors everywhere in the inner solar system, not just in the vicinity of Earth. I’m sure you can agree with that.”

On the contrary, you are postulating a distribution of the meteors in the inner Solar System which cannot exist in the preseence of the Solar gravitational field, the planetary gravitational fields, the forces of the Solar Wind, and electro-static forces. The planets formed as they did due to the harmonic wave distributions resulting from the gravitational forces, Solar Wind forces, and electro-static forces; see Bode’s Law. There is every reason to expect an interstellar debris field would not have a relativley eveen distribution of meteors in a field the size of the inner Solar System. Even if there did exist such a debris filed and the Solar System encountered it while orbiing the hub of the Milky Way Galaxy, such a debris field would become disrupted and non-uniform in distribution upon encountering the gravitational fields of the Solar System and long before passing through the Oort Cloud on its way into the outer Solar System. The inner Solar System would then encounter the disrupted population of meteors as a series of streams or torrents between quiet periods between those streams and torrents. Again, the debris filed could not enter the inner solar system as an intact field of meteors. You simply cannot have “more meteors everywhere in the inner solar system” because the various mentioned forces remove them from some regions of sapce eveen before they can arrive in the inner Solar System. Any new debris field created within the inner Solar System by something like a collision between asteroids will immediately begin to dissipate into a non-uniform pattern due to the differences in the forces acting upon them.
