Oh good! Maybe we can find a benevolent God on the next rock.

UNcertainty is easier than KNOWING whether there is: A) an alien we can have a conversation with or B) absolutely nobody else in the universe we could talk with.

This kind of data from Kepler represents the best kind of science NASA is doing. So much has been said about the space shuttle-- but it hasn't contributed in terms of real science very much-- despite the hugh amount of money spent on it. The Kepler spacecraft with it's planet counting mission is operating on a shoe string budget compared to the shuttle.

There are 1,234,567,890 planets that are like earth that we can live on. We should go soon.

But there is only one God and one inhabited planet, earth. The rest are to test our faith. God gives the doubter enough rope to hang himself with by musing about wild ideas how we got here or what aliens might visit us, but He also reveals enough to each of us to know what to do and why. It's your choice, you all have free will.

I refuse to believe there is intelligent life on other planets. But then why should other planets be different.

Disappointing comments here. This is about the most fantastic thing I can possibly imagine. Without a doubt there are numerous planets with life just within our galaxy. And there are billions of galaxies. Mind-boggling.

Interestingly,the more planets you identify with the physical charachteristics for life, the more you prove life did not just spring forth spontaneously. Since we are a relatively young star and planetary system, each new planet found that hasn't contacted us just makes it less likely that there is any other life, especially when many of those planets are older. If it CAN happen spontaneously, as some insist happened here, it becomes more likely that it should have happened elsewhere as the numbers go up. No contact from anywhere implies the opposite.

There are an estimated 100 billion stars in the Milky Way and and estimated 200 billion galaxies (of various sizes). The laws of physics are the same across the universe, to think that there won't be another planet with a water and carbon based ecosystem means one just isn't dreaming big enough.
