This is talking about estimated average comet/asteroid impacts, right? If we're going by the average asteroid impacts on even million-year timescales causing radical changes to a heavenly body, we'd end up with no moon. I definitely get this is a limited research here, and I'm not faulting it for that. Its good to know it seems like this kind of cycle wouldn't be consistent in adding organic molecules to the subsurface oceans. But let's not necessarily see this as "there's no way organic molecules could have been pushed down in relevant amounts."
