Extra terrestrial life: do you believe they exist?

[Berkut]

Isn't the Drake equation better? *






* In true languish tradition I've not clicked on the link and read it, so going by the way Viper described it, it isn't that old but gold musing.

This is a modification of the Drake equation, replacing someone of the variables that are now roughly known, and removing "how long does intelligent life survive" variable.

It is asking a slightly simpler question...

Which to me seems like almost the key variable, as it's linked to the probability of us ever being able to communicate with them, rather than say just conduct future extra-archaeology.

It's a key variable if the thing you want to think about is "Are we ever going to have a chat with extra-terrestrials?" but not important at all if your interest is "What are the odds that human intelligence is truly unique?"

Exactly.  The work reads to me as an attempt to quantify the highest chance of intelligent life developing on a suitable world consistent with the human race being unique in the history of the universe as an intelligent life form.  That number is very very low based on what we know right now.

Voted no, despite the probability sums backed by scientists, because i'm assuming the poll is about intelligent life. I do, however, think it's a dead cert we'll find evidence of mono-cellular life elsewhere.

It is interesting that so many people "believe" in extraterrestrial live despite zero evidence that it exists.

I think there is some evidence that single cellular organisms exist outside of earth.

Only the ones we brought into space with us.

I thought there were possible residue left behind on Mars maybe possibly indicating there was bacteria there at some point?

[Eddie Teach]

I thought there was evidence there had been life on Mars at one point too. Dunno if it's my faulty memory or sensationalist reporting to blame.

There have been claims, but each one falls apart when under scrutiny.

Links? Evidence has also been found in meteorites as well I had thought.

Links to what?  It's hard to link to a negative.  Not a lot of news stories say "Nothing here!".  You are thinking of a meteorite found in the 1990's where a few scientists thought some mud might be fossilized bacteria.  Here's a link that NASA put out concerning that meteorite.  http://www.nasa.gov/centers/johnson/news/releases/2004/J04-025.html  Several years later.  There is no particular reason to think it contains fossils.

No I am thinking of the Meteor in Sri Lanka a few years back.

Links to what?

Well where do you get your information? Meditation?

[Razgovory]

I had to look that one up.  Turns out it wasn't actually a meteorite.http://www.slate.com/blogs/bad_astronomy/2013/01/15/life_in_a_meteorite_claims_by_n_c_wickramasinghe_of_diatoms_in_a_meteorite.html  Where do I get the information that something is not there?  That's sort of a difficult question to answer.  I haven't any good evidence  that indicates there is extraterrestrial life, therefore I see no reason to believe in it.  It's not a source of information, but a lack of information.
