I guess given the sheer numbers of stars and planets out there it's probably a statistical certainty that some other sort of self-aware intelligent life is out there but....

It took the better part of 3 billion years for multi-cellular life to evolve from single celled organism and then another 600 million years for something smarter than an ape to come along, and then a couple hundred thousand years for that one-off species to develop the cultural knowledge to understand and contemplate space travel. So at least in the n of 1 we know about some species like us appears to be exceedingly rare and even for 99% of our existence even with our brain power it didn't lead to the science/technology to understand the workings of the universe.


Ah, but that still just boils down to a math problem in the end.... You may be presenting a super tiny fraction, but if you multiply it by a big enough numerator, then the probability is no longer tiny, or even fractional.

Yeah but we don't know the probability of two significant "state changes" occurring because all we have is an n of 1 here on earth. I would argue both are probably very rare given of the billion upon billions of species that have existed each (as far as we know) has only occurred once; multi-cellular life and language.

I honestly don't know about the probability of intelligent life on other planets, but you are wrong on at least one count: multicellular life has developed independently many times during the history of the earth. Plants, fungi and animals are three examples of multicellular organisms that everybody knows :-) and they all have developed into multicellular forms from unicellular progenitors independently of each other. But there are actually many more lesser known examples: http://onlinelibrary.wiley.com/.../bies.201200143/full

Thanks, I stand corrected then.

Um, you must be new here. When someone points out that you are wrong you are supposed to double down and call them names.

Please do better next time.

How does Danny Hart sit down with balls that big?

When you're wrong, you're wrong. I'm working off of probably 30 year old high school biology knowledge on this one :)

Although (in attempt to save face) it's still true that it took a very long time for multicellarity to evolve.

But it really only took a "long" time relative to our perception of scale... When we have what appears to be a very low probability based on billions of examples here on Earth, you gotta pivot and try to grasp that billions or even trillions of species is still a tiny sample size across the entire universe.

And based on the fundamental concepts of natural selection, evolution is not 'optional' ~ mutations themselves may be random, so you can't say that humans or any other life form is a 'required' outcome or endpoint, but the fact of evolution is imperative in the sense that natural selection never takes days off, so once you have genesis, some type of higher-order organism is at least probable if not inevitable.
