It has been difficult to confirm the claims of giant ice meteorites encountering the Earth, or to support this model against many criticisms which have been advanced against it. Here are a few of the reasons for a skeptical viewpoint.
- It is difficult to explain the absence of any visual evidence for these bodies. They would need to be cohesive enough to survive a lengthy period in the inner solar system without fragmentation and evaporation, yet fragile enough to break up far above the atmosphere into pieces uniformly so microscopic that a plasma trail (meteor) doesn't form.
- The impacts of these same bodies should be visible on the moon, which has no atmosphere to cause them to burn up. It is not.
- There should be seismographic evidence in the instruments which were briefly operated from the Apollo landers' science packages to show contact with the moon. There is none.
