>evidence of early bombardment on Earth >assuming that this might not have happened on the Moon
That's a pretty big assumption, because it assumes that the Earth is somehow special in "attracting" (outside of gravity, but we're not talking about that, we're just talking about "targeting") bombardment and the moon is not, while both occupy a similar orbits around the Sun.
There's no such claim in the article or summary. The moon rocks don't have the full surroundings available to make sure it wasn't just existing zircons knocked about by an impact rather than formed in that impact. Evidence from the moon is being used to time the late heavy bombardment. So we're no longer sure the evidence we found on the moon is good enough to narrow down the timing as much as we thought.
Did anyone else think this was going to help them pick up chicks? ;-)

I don't buy this doubt. It fails the laugh test.
