Do “Alien Species” Exist in the Universe? What’s the Drake Equation Have to Say? #2

Some blog followers might be interested in a discussion-list post “Do ‘Alien Species’ Exist in the Universe? What's the Drake Equation Have to Say? #2” [Hake (2014)]. The abstract reads:

********************************************
ABSTRACT: Guy Brandenberg and I, in an exchange on EDDRA2, each erroneously assumed the intent of the other’s posts. The misunderstandings could have been avoided had Brandenberg, in response to my post “Do ‘Alien Species’ Exist in the Universe” at http://bit.ly/1kHEm0i , written something like:

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~
“Alien species” may or may not exist in the Universe, but at least we now know the answer to the question “Is there life on Mars?” It’s YES. We know this because NASA and the Soviet space agency sent it there on rovers etc.
~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

Brandenberg (2014b) went on to write at http://yhoo.it/1fciR0J: “We are, however, beginning to fill in some of the ranges of some of the variables in the Drake equation, and alien life is definitely a possibility in my mind. . . . . . . .”

But in “ ‘Where is Everybody?’ Failure to Detect Intelligence in the Universe is Due to Failure of Universities Throughout the Universe” [Hake (2013)] at http://bit.ly/H3roIC (6.8 MB) I wrote:

According to Goldsmith and Owen’s The Search for Life in the Universe http://amzn.to/ij9jKj: “When we multiply all the factors . . . .[[in the Drake Equation http://bit.ly/16MYTZ2]]. . . .together, we find that the result for the number N of intelligent civilizations in our galaxy now with communication ability and desire equals L/40, where L is the lifetime, measured in years of a civilization once it has developed the ability and desire to communicate with others.” Suppose L = 200 years, as appears likely for Planet Earth, . . . . .[[According to Wikipedia, Guglielmo Marconi http://bit.ly/1c4nqeL started transmitting long distance radio waves in the early 1900s.]]. . . .. then N = only 5 civilizations in our galaxy are trying to communicate with us. . . . . . . .[[or effectively zero (0) within the considerable margin of error]]. . . .
