That's extremely odd, when the all-knowing gods and wise old wizards
of these DARPA saturated Usenet/newsgroups have become so unusually
dead quiet on any topic the least bit related to Venus. Of course
that's only because of what I'd uncovered that even a 5th grader
should have figured out as of 8+ years ago, if not a whole lot before
then.

If other intelligent life existing/coexisting on Venus is too much for
your pathetic, snookered and dumbfounded brain to fathom, then don=92t
bother with most other reality issues because, you=92ll only get those
annoying headaches once realizing how your government and of its faith-
basted Zionist/Nazi puppet masters have been screwing you and most
everyone else over for decades.
