They are rocks, composed of substances all of which have been found on Earth naturally. Tell me how the moon was the only possible source rather than doing your usual blind insistence and buying into hype.
I'm not a qualified geologist, so I defer to the writings and works of those who are. In brief overview;
https://www.lpi.usra.edu/lunar/missions/apollo/apollo_11/samples/In more detail, see sections 6, 7 and 9 of;
https://www.lpi.usra.edu/publications/books/lunar_sourcebook/The chapters summarise the results of the work done on the samples, and the references section tells you who did the work, where and when, and where it was published.
If the rocks were of basic Earth origin, dontcha think one or more of these folk would have noticed?
Oh, and I almost forgot - one of the Apollo 17 astronauts was a geologist, you can read his account of the big 'field trip' here;
http://fti.neep.wisc.edu/neep602/LEC1/trip.htmQuoting and paraphrasing from various sources;
The rocks are similar to Earth rocks, but not identical. One obvious difference is that they all had micro-meteorite
impacts which Earth rocks don't have. Also they were very very dry, lacking in volatiles and not hydrated like their
Earth counterparts. And many are as old as 4.5 billion years old, older than any Earth rocks.
Some of the conspiracy theorists say that they are lunar meteorites - but the lunar meteorites are rare, and
not known at the time. The first lunar meteorite was discovered in the 1980s.
Others think unmanned rovers on the Moon brought the rocks back - but if so, how do they exactly match the rocks the
astronauts pick up in the videos? Also, the Russian Luna program returned a total of 0.326 kg of samples in three missions.
Apollo returned over 380kg in 2000 separate samples,
Lastly, look over this 2009 paper examining isotope ratios in this rock, and giving new results about the moon (you'll need
to register and login to do so)
As someone said; Could you imagine that back in 1969 some scientist involved in the fake anticipated that some time in 2009 someone would examine this rock and want to find out the isotope ratios of Argon, and manipulated them to make them appropriate for a an instrument not yet invented to answer a question not yet asked?

Honestly, I could go on like this all day, finding more and more interesting articles about the lunar samples, but it's not
my prime area of interest, and I'm only putting this together because you asked, so ...
No doubt you'll insist that I should do some more "legwork", but as I say, I'm not a qualified geologist. Those who are, are
in no doubt about where the lunar samples came from.
Is that enough of me "angrily asserting" for you ... ??
