the only planet we could go to is mars. venus to too hot. jupiter, saturn, neptune, and uranus are just gas. and pluto is too cold. so our only option is mars. if that turns out to not work then we will not reach a planet for hundreds of years because with our technolohy right now it would take 75,000 years to get to the nearest star, so that also means 75,000 years to get to the nearest planet in that system. and we have found an earth like planet in another solar system, but its lightyears away and we dont have even close to the technolohy to get there.

Of course its true, they basically used the model of our solar system and made predictions with the new data of planets likely to hold life, even if its not as evolved as the life on earth, the chances are still in favor of there being some type of life on those planets, even if its microbial life or life that took a totally different evolutionary path. I mean its not to say they know for a fact, but the next telescope they are putting up into spance (James Webb Telescope) can actually tell through atmosphere composition weather a planet has an earth like atmosphere. They take onto consideration if the plant is the same size as earth, that would determine if the human bone structure can withstand the new planets gravity. But all in all its a huge leap forward in science, but I'll be more siked when they figure out how to traverse the universe in human's life time in order to reach any of those planets.

If a planet could sustain life there would be life on it unless the planet was very young and life had not yet had time to emerge. Such a world would be the ideal world for future humans settlers. If the planet is young then its parent star is young too. We could seed the planet with terrestrial organisms and they would flourish. And eventually life would be as strong and varied as it is on earth. Only we would have gotten a 4-4.5 billion year head start on a brand new world that might live on for another 10 billion years...
If there is advanced life on that planet, there would be it it had been able to sustain life for a few billion years, then we would have to contemplate what effects that life would have on us and what terrestrial life would have on it. It could be that terrestrial life would annihilate the indigenous life. And how can we allow for the first contact we have with alien life to spell the end of that life? A world that is already alive would be hands off for human colonization.

Right now there is just no way to reach such a planet. And even though I'd like to see the human race become a space-faring culture, I have pretty big doubts about our ability to ever hop about from stellar system to stellar system.
So unless there's some huge breakthrough, I doubt if we'll ever get to an Earth-like planet even if (when) we spot one.
It's a pity.

uninhabited... that's pretty broad coverage.... how about the flies?... the slugs?... the fish in the waters?... if it will support life, there will probably BE life there.... and it doesn't matter if it's only bugs and turtles, it's still THEIR planet.... our presence will cause an upset and we have no right to do that.... so, morally, I'd guess that those that feel as I do would fight the colonization tooth and nail.....
the only way we can move to another planet without this problem is to find one that can be 'terra-formed' to suit us, where there is NO life to be found in any form, before we got there..................

Let's hope that the Americans don't get there first and make it "safe for Democracy.............".
How about we stay here, clean up our own beautiful planet and then contemplate our navels for a while.
EARTH MEN YOU ARE LIKE A FUNGUS TRYING TO DEVELOP AND POLLUTE THE WHOLE SYSTEM.
P.S. Is there oil on Pluto or wherever?
CLEAN UP YOUR OWN BACK YARD, EARTHLINGS

If we could get to it and sustain a colony on it. Just because of overpopulation and cuz the governments of the world never see a reason to spend their money on something more important. (i.e. AFRICA IN CRISIS AND NO ONE SEEMS TO CARE)

Oh, if i ever find out a way of starting over, have fresh natural mineral resources, and ensure long-term survival of our species, I would surely nuke it!

YES - pretty sure we inhabit, we are hard headed.
