That is not at all compatible with the simple fact that we exist. I have asked you twice already to demonstrate your supposed simple mathematical proof that alien life absolutely cannot exist. You have twice failed to address that challenge.

The be precise it proves nothing. What Drake equation provides is an educated guess about probability of sentient life in our galaxy based on number of locations suitable for life as we know it. Unless one is somehow convinced that life is unique to Earth (or that Man was created by God strictly for Earth) it actually provides pretty good probability of existence of a sentient life in our Galaxy.

Probability of sentient life in our immediate vicinity (which ~1400 light years is) and at the same extremely brief moment of human evolution where we are already capable of detecting signs of such existence, however, is extremely low.

As far as insults go - going to school would help to better interpret such concepts as probability and how it relates realizations over sufficiently large ensembles. Also what is "proof" is not very hard concept in mathematics, even someone with relatively limited education should be able to grasp that.

Did it prove there are no aliens, or did it prove we would never meet them (because they are too far away)?
Surely maths will say there must be life out there just based on odds and the number of planets and suns out there.

There is justification for this as well...we are indisputably in possession of the most advanced intellect and society that we have any evidence of.

Of course, lack of evidence of something is not evidence of the contrary, most certainly not when no real investigation is currently plausible.

Saying we are alone in the universe is the same as saying a given building is empty, without ever looking inside.

I wasn't directly replying just giving my thoughts, and yeah, we are terrestrial primates, and still very closely related to life we like to think we're superior to because of our more finely developed communication skills.

And yes, absence of evidence is not evidence of absence, as the saying goes.

The problem with humans is were think we are so special and above everything else. I for one look forward to the discovery of other life, that way people wake up and stop arguing which made up fairy tale is the best.

P.S. If math is made up stop using all technology now.....I suspect your PC is on and working right? k then your full of it. lol

The problem with these mathematics is that they're all based on assumptions. Many of the assumptions (i.e. percentage of stars with solar systems, percentage of solar systems with suitable planets, etc) are completely made up. We have not observed enough stars with these attributes to come up with any sort of meaningful statistic.

However, even if we gave each event that we know is required for life an extremely low probability, the vast number of stars out there makes the chance of life existing elsewhere extremely high. The real question then becomes, what are the odds of intelligent life forming within our own galaxy? And given the age of our galaxy, what are the odds that intelligent life formed and advanced before us? These are the numbers that are being fudged, because we have no real data of any kind.

clearly you haven't taken a probability course in your life. Yes we don't have the exact numbers for each and every star and planet, but does that matter? even if you consider our sun's solar system to be the rarest thing in life the sheer size of our universe makes the probability of not only finding another planet with life on it, but finding a planet with your evil twin on it. In any case the odds are never zero when you're dealing with infinite.

Clearly you didn't even bother to read the second part of my post and jumped to conclusions about what I was trying to say. And yes, I did take a statistics course, so clearly you don't know anything about me either.
