is that Earthly abiogenesis is at a wall and therefore the extra-terrestrial seeding notion is the primary theory at this moment (mostly due the the chirality conundrum I mentioned before).

No, it is not "at a wall" not for chirality, or any of the "life takes too long" arguments. Mutational clocks could have been moving faster, or slower before mutation was the right thing to call what was going on. We could be way wrong about exactly where, on or in the planet, biogenesis took place. panspermia is a hot conjecture, but that's all it is at the moment. You have to discount the "oops, dropped the beaker" factor before you go looking seriously for explanations for anomolies outside the present paradigm.

Maybe my brain is being controlled by panspermian extra-terrestrials, but I can't seem to remember how to find old threads I've bookmarked--can someone help me?

Please enlighten me with a logical argument against the chirality conundrum, then.

I have never seen a plausible scenario to explain why all organic matter (or almost all) is L and not D. I have heard somewhat plausible theory that UV light "somehow" changed the chirality of space-based organic matter, but that was due to its lack of sheilding by an atmosphere and its orbital proximity to the sun.
