There's no need for the aggression. We're two grown-ups here, having a discussion about a subject we both find fascinating. That aside, here's some elaboration. Trillions of meteorites have landed on the Moon's surface since its formation. Some of these may be remnants from violent collisions between other planetary bodies. A few of these events may have happened at a time where life was starting on Earth. An tiny portion of these pieces of rock may actually contain fossil evidence of early life, in the form of bacteria or complex biochemistry. Similar evidence that once existed on Earth is likely to have been destroyed by our active geology, or by more recent biological processes. The likelihood of life being preserved in this manner is so vanishingly small that, out of the trillions of meteorites on the Moon's surface (an area around 20% larger than that of Africa), only a minute number of them are likely to contain anything like it. It would be a shame if the key to understanding abiogenesis was lost in an industrial rock-grinder.
