refute this 1178 AD impact by claiming there would have been numberless "shooting star" reports

Sure, but sightings aren't reports, and who would take reports anyway? After all, Dan Rather wasn't around then to place it in the public record. Was he?

I was never impressed by the lack of reports -- the future Nobel laureate claims to have found nothing in medieval literature (20+ different languages) in the two months (!) or so he spend working on his paper.

I wonder what he thinks of the constant bombardment of micrometeors in our atmosphere, and visible any night where the skies are clear and sufficiently dark? I mean, he did say that the bombardment should still be going on.

Doesn't mention this smaller 1953 impact, and the consequences that should have resulted.

Or the fact that these high velocity impacts mostly lead to vaporization.

Or the fact that an impact fireball on the Moon would be larger due to the Moon's smaller size and density (about 1 per cent the mass of the Earth) and cratering more severe than here on the Earth.
