i would rather think they are billions of earth-like in the universe
OC they all got their own form of life



You wouldn't be that far from the truth, I think...

There probably are billions of Earth-like planets in the universe which means there may be a few or none on average per Galaxy. This is my belief. Kepler is just starting of course; but no planet of Earth size has been found in the habitable zone of any star. More data is needed and will be forthcoming I suppose. After we have a catalog of truly habitable, Earth-like planets we must investigate if these planets have the other list of requirements for life to start and evolve.

Super Earths will attract/retain Hydrogen and other gases and hence will not have a useful atmosphere.

It's all a moot point unless or until we have a way of getting there either in person or robotically

Even if there are earth-like planets, they would need to be at a comparable point of evolution for us to receive any signals. That is, if they are even 100 years less advanced, they would be sending no signals, and if they are even 1000 years more advanced, they might be sending no signals either (or in a form we would not understand).

For that matter, everyone seems to assume that advanced life forms will be zooming around in rocket ships and inhabiting large cities. I think it is at least as likely that advanced life may learn to subsist will less energy and mobility. The reasons you move around are mainly to get materials to support life, or information on where to get such materials. Advanced life will have all the knowledge available in the universe, and know how to live where they are. There probably won't be that much need for communications at a distance.

and what tells you that, obligatory, a sentient race would always go for radio signals, exclusively ? what if there would be another way , 98% of all races in the universe would go, and us, human races , we never thought ? we never imagined ?

That is a fair point to be made. Look at David Bowman Star Child in the Space Odyssey series.

Someone once said, I forget who, that the whole universe that we know, could be nothing more than a speck in someones eye in another universe. Tricky things these universes.

Why are we going through all this expense of finding another earth? We can not go to these planets in a several thousand years just to explore them. I think its a waste of time because it will take technolgy a million years to catch up.Mankind has to harness asteroids and be able to move them. We have nothing in place. Even to find one and do something about a planet killer we havent a reliable way to do something. To do anything am asteroid has to nbe located out about jupiters orbit. If it comes out of the sun we wont see it. We have to do this or have something in place and a nuke isnt an answer then its a shotgun blast with multiple impactors and radioactive. We are so far away from these planets we could never get to them.

Humans are inquisitive species by nature. Unfortunately there are so many things that will remain a mystery cause we'll never be able to apprehend everything. Our minds just can't cope with things that are beyond comprehension.

It seems we all agree that there is at least millions of earth like planet in the universe and at least couple of thousand with all the earth feature (element, moon etc) So then we got two possibilities either go there or analyze from here. As some said above we did not yet confirm life on Mars so what about a planet hundred of light years from us! It will take time for human or robot to step a foot on another earth like planet outside solar system. Not in our life time that's for sure :-(

What makes SETI very very cool is that it opens a window of opportunity for human to evolve faster in a certain way. In fact if we intercept E.T. communication we may get new alien technology and accelerate rate of development. Also for us, we finally have a 100% proof that there is intelligent life in the universe. Ok we may not walk on that planet or have a two way communicate with them (in our life time) but at least listen/look to them.

Still too little data to go on yet. With all these planet discoveries it sometimes seems that we know more than we do.
While its clear now that at least most if not all single stars have planets the sheer number, and characteristics of these systems indicates that we know very little about planet formation dynamics. Certainly almost everything I learned in college about planetary formation and dynamics hasn't stood up.
Bear in mind that our observational techniques are still biased toward finding non-solar type systems. Giant planets very close to their stars or planets around very small massed stars.
Just a question to throw out there- Our solar system is dominated by Jupiter. With an orbital period of just under 12 years how far would the Sun have to be before we could not detect Jupiter gravitationally.
Kepler might detect a transit once but it would be 12 years before we could verify it.
I hesitate to speculate about how many Earths there are until we have a clearer idea of mass distributions.

I'm with you David. The present methods used to detect planets around distant stars can only find those that are within a narrow set of circumstances, basically short orbital periods. But even with limited parameters they are still finding a bunch of what are hopefully planets. When I was in college we were taught that only a very few (less than 10%) stars were suitable for supporting a planetary system. Now it looks as if it is the other way around. But knowing they are there is an even greater tease as we still have no way of determining through means of our own whether they are inhabited. So ET is still going to have to contact us if we hope to find out any time soon how alone we are.
