I agree more with Rodrigo. Although, there may be life out there similar to Earth's, I think it's faulty to assume that if there is any life out there, intelligent or not, that most, if any, is formed or even made of the same building blocks as us. Humans like to think we know more than we do.

And as far as communication goes, I'm sure there are forms of communication that we just can't comprehend. Again, we're not necessarily as intelligent as we might think (^_-)

The conditions that existed for life to begin on earth will be replicated at some time on millions of planets if the numbers we are beginning to realize are true and there is reason to believe we have underestimated the numbers once again.

If life is intelligent, no matter what form, we will be able to communicate or they aren't intelligent...simple.

Slight differences? Probably insignificant in the face of millions of EXACT circumstances at one time or another in the development of a million planets.

The numbers, so far, indicate MILLIONS of intelligences in the known universe.

I don't think will be easy to find "intelligent" life AND that we will able to communicate.
The advent of RNA / DNA is so unique to earth, and this planet conditions, that on another place if matter conceive "self awareness" it will be so different that probably we wont be able to classify it that form as " life " .
Ok, we know that there are organic compounds floating around in space, but if they get into grouping in self replicating organisms, whatever comes from there will be so so different,.. that the most we will be able to do is contemplate the variety ;-).
We are the result of the first "kaleidoscope" combination that worked here on earth, and covered the globe on it,, and everything is just repeating over the same formula, on another planet if that set of first combinations is just slightly different on the microscope scale.. I can't even imagine it. :-)

I think it is more at achieving civilization rather than intelligence. As to quantum mechanics, I believe in the uniformity throughout the universe no matter what you base your science on.

i totally agree.
Comment by E Alsmann on November 23, 2009 at 12:37pm
@Ogden Lafaye: unfortunately that is not entirely true. Every law of physics gets thrown out the window when dealing with quantum particles; however quantum physics has its own set of laws that are still being written...
Comment by Ogden Lafaye on November 22, 2009 at 8:23pm
I would bet the ranch that the laws of physics and constants of nature (conditions and parameters) are uniform throughout the known and unknown universe.

We are a natural evolution and there is no reason to believe that there are not other naturally evolved intelligences throughout the vastness of and beyond, far beyond "Hubble Space".

@jstn earthling: heres a recent article about NASA scientists making uracil in the lab modeling conditions in space.

just found this on an atheists news page, don't know if it's been posted before it wasn't dated 'An elegant experiment has quashed a major objection to the theory that life on Earth originated with molecules of RNA.

John Sutherland and his colleagues from the University of Manchester, UK, created a ribonucleotide, a building block of RNA, from simple chemicals under conditions that might have existed on the early Earth.

The feat, never performed before, bolsters the 'RNA world' hypothesis, which suggests that life began when RNA, a polymer related to DNA that can duplicate itself and catalyse reactions, emerged from a prebiotic soup of chemicals.

"This is extremely strong evidence for the RNA world. We don't know if these chemical steps reflect what actually happened, but before this work there were large doubts that it could happen at all," says Donna Blackmond, a chemist at Imperial College London.'
