Thanks for the very interesting discussion, RadioAstronomer and sleavelessinseattle.
RA, I've pretty much come to terms with the evolutionary mechanisms(not theory, kids) and genotypic representation in subsequent populations based on environment, and relative reproductive efficiencies constrained by limited resources and metabolic waste buildups in a given exobiological closed system(pre spaceflight, even though might occur in a cloud of Dark Matter, since we don't even know what that IS!)...
Given the current behavior of adherents of Wahhabi Fundamentalism's utter rejection of education, equal rights, Their disdain for the scientific method, has anyone done a Massively Parallel Processor Model on how Infinitesmally small the probability value is that a culture of sapient life forms could develop a cosmological view of other life forms and stay focused on R&D long enough to produce a SETI type search, much less Interstellar flight capability during the finite period of Humankinds technological age and coming to visit us for purposes of violent conversion to the ET's version of Sharia for our own good? I'm thinking that calculation won't take long, and the P value will be one of those theoretical numbers so close to null that some hungry grad students will get their advanced degree's based on dimensionalizing it down below the Planck Constant of the smallest unit of size possible in this Space Time continuum...For discussion purposes only ;-D RA, I'll be responding to your stimulating answers seriously as soon as I've establish that my Cerebrum has absorbed sufficient caffeine for my Reticular Activating system to remember to breath for me without conscious mental exertion!...LOL! looking forward to it!!!!
