It is a flawed analogy. Sagan wrote a paper attempting to calculate the effects of a full blown nuclear exchange with extremely variable data.
It turns out he wildly overestimated the impact. But there is still some impact.
Crighton says because the results from Sagan's study were so far off the mark, that Drake's equation is void and thus believing in aliens is a falsehood ?
No. Whatever the values of the variables in the Drake equation, so long as none are zero, there are other intelligent lifeforms in the universe.
That's the usefulness of the equation. I wouldn't count on it to accurately predict how many other lifeforms are out there, but it asks an important question.
I said the Drake equation is not scientific because you cannot test it. Not everything needs empirical validiation for a truth to be recognized. Philosophy has enlightened, giving understanding, long before the scientific method.
No we didn't ? If you're referring to that meteorite found in Antarctica, there is a plethora of studies and peer reviewed papers submitted explaining natural non-organic causes for all of the phenemenon that the original scientists theorized were caused from microbial lifeforms.
The original scientists still believe it is evidence of fossilized bacterial traces, but the majority of scientists who've looked at the matter do not. At best, it's a debatable question. Stating we've detected life on Mars as a fact is incorrect.
You're misreading my statement. I have no idea whether or not life is rare or what the specific density of life is within the universe. But the size of the universe does suggest that no matter how rare it is, there are other lifeforms out there. We are here after all. And yes, that is logical.
I didn't say teaming with life. I said take a poll and 90% of scientists believe there is some other intelligent life out there beyond Earth.
Incidentally when asked this question, much like acceptance in the theory of evolution, a positive answer coorelates directly with the education level of the individual asked.
"All of those structures on the Moon and Mars"
I'm not sure what you mean. If you're referring to the threads I've seen on this forum, Richard Hoagland's and John Lear's arguments, they don't sufficiently convince me.
Let's leave it at that ?

You get one science hack who likes to explore Mars rover feeds from his home computer and declares he sees evidence of fossles -- well, it would be like me exploring the White Cliffs of Dover in England with GoogleEarth and declaring that I found the remnants of Sodom and Gomorrah.
And as for a strip mine on the moon -- I hate to feel like I need to have kid gloves when referring to Lear, given his special relationship with ATS, but I mean, really? That kind of blanket statement and conclusion just shows a real flawed and short-sighted understanding of geological science.
Paradoxically, I agree with some on here who question the expenditures of SETI, and whether that money could be used for Mars exploration instead.
While not in my opinion to prove life once existed there, but instead for the eventual colonization of the next best candidate planet in our solar system to support human life and perhaps even terraformation.
