I did--it's hokum.

So explain Carbonaceous Chondrites.


Coming right up...

" A rare type of stony meteorite which contains large amounts of the
magnesium-rich minerals olivine and serpentine and a variety of organic
compounds, including amino acids. Although fewer than 100 carbonaceous
chondrites are known..."

Do you *really* think that's where Earth's petroleum came from? Rare
meteorites, of which fewer than a hundred are known? Get real.

What percentage of the rocks that hit in the Age of Planetesimals were
Carbonaceous Chondrites? What is the percentage mass of such rocks that
is organics? What is the mass of the Earth?

The numbers do add up, if you care to look.


Nonsense -- they don't even come *close* to adding up. What part of "rare ..
fewer than 100 known" do you have a hard time understanding?

That's bit's of loose space-rock sitting on the surface of the earth. We
are fairly sure some of the asteroids are Carbonaceous Chondrites.
Carbonaceous Chonrites are rich in volatlies and thus much more likely
to pop on entry to atmosphere.

And, last I looked, there was less oil than crust, and there isn't a lot
of crust on the earth... you might even say it was "rare" in relation to
the rest of the planet...
