Since I made no such claim, you were indulging in the same
misleading noise that you have spewed again, just today IIRC,
against John Harshman on the "Hiatus" thread.
[Yeah, you didn't make the stupid mistake of confusing
my question with a claim, but that leaves you with having
made a bunch of irrelevant self-serving noise. That
is the sort of thing you love to do, and to keep projecting onto me.]
I ignored the Tweedledum-Tweedledee "battle" between you and
Harshman on that "Hiatus" thread, and instead gave a rousing
"Welcome back, Riichard!" to Norman instead, and proceeded to
let him know indirectly that I'd make it very easy for him to
make up for lost time wrt scientific discussion.

It's a subsidiary issue. And with this answer to my question,
you've taken away one of the possible ways one could argue for
abiogenesis having taken place ON EARTH.
However, you did give another possible way below, by telling us
your opinion on something hasn't changed:

Well, we happen to disagree on that. Part of the reasoning behind
my hypothesis of DP as being more likely than earthly abiognenesis
involves my belief that abiogenesis that produces something
as sophisticated as a bacterium is a great rarity.
Specifically, a rarity in the "once in a galaxy' ballpark.
But the many "Rare Earth" hypotheses don't stop with prokaryotes,
because they involve the thesis that the ca. 3.5 billion years
evolution beyond prokaryotes is not something that is common;
in fact, some Rare Earth proponents even think our intelligent
species is unique in all the universe.

Most of those would be taken care of by the hypothesized panspermists,
about on our own level but with technology advanced to a level which
we can only expect to attain in about a century from now, given
enough funding. [The level of our military expenditures would be
many times more than enough; OTOH with the niggardly budget NASA has to
make do with, it could take the better part of a millennium.]

Especially by me, n various parts of my very lengthy drafts for
a FAQ. I expect to submit it to the Talk.Origins Archive some
time this autumn.

On a planet with much shallower seas, the equivalent of the
Cambrian explosion could have come within a billion years
of the appearance of bacteria level organisms. [Keywords:
banded iron formations. I've been through this one many times.]

Purely conjectural, but with the threat of a world war including
Mutual Assured Destruction having receded, I think the lifetime
of our species has a good chance of being in the millions of years.

DP only hypothesizes the transport of hardy microorganisms. As
to the physics and economics of the matter, that has also been
dealt with extensively in the latest draft for the FAQ.

The basis has been presented above for why I consider a DP more
likely than abiogenesis ON EARTH. For the rest, google my last
thread on Directed Panspermia.
I trust that indirectly answers your loaded question.

This is another reprehensible practice of yours: you call something
an "obvious lie" without even trying to explain why it is
a lie, let alone whether it is obvious.
Like Ray Martinez, you seem to think that just labeling
something a lie is "documenting a lie."
Correction: I'm not sure Martinez ever went so far as
to *explicitly* claim he had "documented" lies.
