I see what you are trying to say, that there is no hard proof, yet, that other lifeforms exist. But you do have to realize just how immense the rest of the universe is, actually never mind, because nobody can really comprehend the entirety of space. There is so much we don't know or haven't seen that it is sooo nearly undeniable that there is life elsewhere. To think we are the only lifeforms in the universe is an extremely arrogant and plain old stupid thing to say. Everything we have ever known about this universe is just the shores of the cosmic ocean, nobody has ever set foot in the rest of the ocean yet, and most people like you barely have their feet wet.

basically what i'm saying is, the argument is extremely valid.

Spoken like a true person who doesn't quite understand how big space is.

Spoken like a true Christian.

To the people who have a problem understanding what I said: I didn't say that there is no life, but that that arguement is not very valid.

Nah, fuck it. Too many idiots here.

You thumbed me down and didn't even reply to me after I explained what the post was. You're the idiot here.

It's attacking ignorance. People that think because there isn't life in the space they can see, there must not be life at all. It's a quote that attacks that way of thinking. It's not in any way, shape, or form making an argument about life in the universe. Please read before you type.

We have no proof of life existing anywhere else but on our planet. But at the same time, we have no proof that it does not exist.

Said a like a true agnostic ;)

That's exactly how I think about it. And not only about that, but also about God etc.

Exactly. But saying that there must be life because of the size of the space is simply silly.

no, the universe is so vast that the possibility of there not being life anywhere else is extremely small

And that's because....?

Quantum probability says that the odds are better for the power ball to get to 300 million fifty times in a row and for the same person to win every time it hits 300 million than for there not to be life out there. Basically the odds are something like 500 quintillion to 1 against there not being life somewhere in the universe other than earth.

The drake equation conservatively states that there should be between 1000 and 100.000.000 detectable civilizations in our galaxy.

There are between 100.000.000.000 and 200.000.000.000 galaxies in the observable universe..

Michael Crichton: The problem, of course, is that none of the terms can be known, and most cannot even be estimated. The only way to work the equation is to fill in with guesses. [...] As a result, the Drake equation can have any value from "billions and billions" to zero. An expression that can mean anything means nothing. Speaking precisely, the Drake equation is literally meaningless...

yes, it is an estimation, however, i refuse to believe that the chance for life to exist on a single planet in a galaxy is [1/100.000.000.00 : 1/200.000.000.000]. The building blocks of life are not that hard to make, it's just organic chemistry.


Oh, and this is all assuming that the only kind of life possible is carbon based.

I don't say that there is no life. I say that the arguement of possiblity of life outside the Earth just because space is big is not valid. If we start defining life, this will never end.

and im saying the argument that the chance for life existing outside of earth because of the sheer size of the universe is solid, simply because the universe is so vast that the odds of it not being there are too small to even be considered.
