how many suns do you think are in this universe? what about milkways? do you really think there could be a posibility that there is not other life forms out there? hell we are them!

who says there isn't any?
they proved it mathematically, I guess they have to figure out how to test it then?

I believe life exists on other planets, but I don't believe that life has visited us or even knows we exist. Even from a relatively close distance across space, Earth is far too small a planet to be seen and much too close to its sun to be observed closely. If our solar system was being observed from some other point in the galaxy, Jupiter and Saturn would be discovered long before Earth, if it ever was. So, unless some alien intelligence had picked up some of our radio transmissions, they wouldn't even know to look our way, much less waste amazing levels of resources to send wave after wave of spacecraft here to perform enemas on cows and doodle on wheatfields. Now, it is possible that an alien intelligence has picked up our radio transmissions, but as these transmissions have so far only penetrated about 100 light years into space, that intelligence would have to be 100 light years to us or closer, and would only now be picking up transmissions that were made 100 years ago. And even if they started sending back a message tomorrow, if they're 100 light years away, we won't get it for a century.
Of course, there could be intelligences that are much closer than 100 light years away, but radio telescope technology has been scanning the skies for 50 years now and not received a single message from anywhere. So either there's no intelligent life at >=50 light years distance, or there is but it hasn't yet developed radio technology, or they're deliberately not sending anything out into space, which would be impossible. This would mean to me that any life with intelligence <= ours exists beyond the 50 light years distance, and that's pretty far away.

unless they don't use radio technology. otherwise good assumptions...

They actually have an equation that estimates the amount of intellegent life in the universe.

i think some of those questions need to be more detailed, such as "what conditions are necessary to support life, and on how many worlds are those conditions present?"
i find the "answer" to "% of those who want to communicate" interesting... 10-20% only? pretty lonesome aliens.

To put another angle on it there is also the Fermi Paradox, which I suppose goes something along the lines of: If there is intelligent life out there where are they? I guess a craft going even a fraction of the speed of light over the course of the existence of the galaxy could travel end to end. Robot colonizers could land on a planet, use it resources to build more colonizers and continually expand outward etc...

Plus sometimes I personally think about how neccesary developing intelligence is. A brain like ours is great for helping our survival, but its certainly not required. Sometimes it seems to me we got lucky that our ancestors faced enviromental & selection pressures that stimulated our minds.
Anyway I believe there has to be life out there. But intelligent life? In addition intelligent life that devolps harnesses radiowaves and spacetravel. Though it seems the Drake Equation is more than broad enough currently to accept all sorts of opinions.
