Toysalot,<br><br>What kind of life? Basic bacterial like organisms or creatures with intelligence and even technology?<br>If it's basic simple life you mean, there may have been such life on Mars, right next door.<br>Not confirmed, but tantalizing evidence of it has been found.<br>Some of Saturn and Jupiter's moons have the potential for simple life too.<br>Life, as amazing as it is, is merely a function of chemistry - given enough time and the right ingredients.<br>But for complex life ... we can't do much more than confirm the existence of<br>other planets around other stars right now, (and this is within the past 20 years!), let alone determine their climate.<br><br>Our search for extra terrestrial intelligence is limited by our current level of technology and understanding of life,<br>which is largely limited to carbon based Earth-bound life.<br>Keep in mid the farthest we've ever been is our moon,<br>the farthest any of our probes has gone is a now dead Voyager II, launched in 1977,<br>which is about 1% of the way to the nearest star about now.<br>The farthest any of our radio waves have traveled is about 76 light years in all directions away from Earth.<br>(The 1933 Olympics held in Berlin was the first event broadcast with enough power to<br>sustain a coherent artificial radio signal out in to space).<br>That means that the Earth is dead center in a spherical ball 152 light years in diameter<br>of artificial radio noise we've been making since about 1933. <br>That's how far OUR radio noise has traveled.<br><br>For any intelligent space-faring creatures were to detect us, they or their instruments would have to<br>be within that 152 light year sphere of our radio noise...assuming they'd even care or be monitoring<br>radio waves.<br><br>Seems like a big area, doesn't it? A sphere of human radio & TV broadcasts 152 light years across?<br>This Galaxy is 100,000 (one hundred thousand) light years across. Not such a big fraction afterall.<br><br>Also, if an intelligent alien race with technology were broadcasting,<br>our ability to detect it is limited by when they started broadcasting, and from where,<br>and if the technology is even known to us.<br><br>The enormity of time and space all but guarantees that there is life elsewhere,<br>but the spans of time and space between such life will likely keep each ignorant of the other.<br><br>Greg

Only in our finite solar system........... And the jury is still out on a lot of those! To even try and say we are it??? Wow............ Signs of life.....Would we even know what to look for, does it all have to be carbon based, is water really necessary for life?? I dunno........ Greg is the guy to come up withall of the web sites supporting, or disproving the many theories.....<br><br>But you trust the knowledge of MAN to make a positive statement like that?? Hell, through advancing technology we are finding new species of plant and animallife right in our own back yard on a daily basis and we can't even figure out a way to get man past the moon and it's doubtful that may ever happenagain!! And?? Who says we haven't found life? Do ya think we would be privy to such world changing knowledge?

<blockquote> And?? Who says we haven't found life? Do ya think we would be privy to such world changing knowledge?</blockquote>Yes!! An X-files angle right there.........you know how I love my X-files.<br><br><br>

<blockquote> Toysalot, <br><br> What kind of life?</blockquote><br>Life like us...a civilization that sustains life and survives and breathes air like we do. Human or another like being that builds things and makes things andcreates life structures etc.<br><br>You know...LIFE!<br><br>Nothing proven and many many many IFs don't count in my book. 'If this' and 'If that' could be said for many many educated guesses butnothing has been proven<br>

I know it's unproven, and might never ever to able to be proven, but I would put all my money on YES, there is life outside our galaxy. Why wouldn'tthere be? We are so small in a vast universe...<br>We could argue about it, but it can't be proven either way. I'd put my money on "Life Beyond"...<img src="http://static.yuku.com//domainskins/bypass/img/smileys/alien.gif" alt="image"><br>

Humming the X-files theme music right now. (Greg is chuckling to himself somewhere.)
