Yes there are earth-like (rocky, terrestrial) planets that we now now about. Though Bob B may not.
There was tremendous interest in the potential for life of Gliese 581c (of 5 Earth masses) when it was first discovered on April 23 2007 and reckoned to be in the habitable zone. (That assessment has since been revised but Gliese 581d (of 7.7 Earth masses) may still be habitable.)
The star Gliese 581 is a red dwarf, that is 20.4 light years away in the constellation of Libra. That is about 120 trillion miles, a mere hop, step and a jump on a cosmic scale (it is the 87th-nearest star to us) but at our current fastest speed attainable (65,000 mph of the New Horizons probe, heading for a 2015 rendezvous with Pluto) it would take 300,000 years to get there.
Until faster propulsion methods become available, it is simply not practical to send even an unmanned probe in that direction. There are nearer planets (Epsilon Eridani b at 10.5 light years away and Gliese 876 b c and d at 15 light years away) but the distances are of the same order of magnitude. Until we can get journey times down to less than half a human lifetime (i.e. travelling faster than half the speed of light) any crew we sent would either be dead or geriatric by the time we got there, and crucially, from the point of view of colonisation, all the woman crew members would be post-menopausal and the colony could never breed and reproduce to sustain itself.
So, literally, and metaphorically, we have a long way to go yet! But the knowledge that the Sun will start to swell and become a Red Giant within the next 5 billion years, and the necessity to decamp to a habitable world elsewhere if humanity is to survive does mean that this set of probems will need to be solved and viable colonies will need to be established at some point. It is not a probem we can postpone solving for ever.

Not with our technology. First we haven't found the planet yet. That's like your a lightning bug flashing and your looking for another one to flash simutaneously on the other side of the planet. That's hard.
And second we do not have viable transportaion to ge us there once we've found it. My guess is the planet will be several million light years away!

That would be nice, but it's very unlikely -- at least in the forseeable future. There is a distance of 4.3 light years between us and the nearest star (Alpha Centauri). It would take over 100,000 years to get there in a vehicle traveling at 25,000 mph, and there isn't even a planet orbiting Alpha Centauri.

I do believe that in the future it will be entirely possible!. we lack the technology right now, for extended space travel.
At this point they are trying to create an atmosphere in planets of our solar system,(mars),but how long will this take?, would not serve any purpose for the future generations, if it succeeds.
To travel to other galaxies, or solar systems similar to ours,
within our galaxy, is imposiible due to lack of means of travel.
They are working on ideas for travel, that will surpass
even any dreams of such speeds, again if they are successful!.
I would say trips like that will be possible within the next 40 50 years, and I may not be around to witness it!

Not yet, but mabye in the future. You see, we think we found another Earth-like planet, but with our current technology, it would take us about 200 years to get there.

There are no other Earth-like plaents we know. We cn get to any planet in the solar system, but it takes months or years. To get to other solar systems would take millenia. To put it into perspective, it will take the voyager probe, which left our solar system a few decades back, 80 000 years to reach the next star.
Planned ships mighgt be able to do it fifty or so, but they require technology we can't currently use reliably.

Actually,in the future,you humans will discover many ways to travel faster than light and you'll be able to go far away in the distant,dark universe.

that's achieveable, yet do you think of it may in basic terms be one actuality tutor? actual they could want to broadcast a minimum of one tutor for each united states, or perhaps each and every family contributors or guy or woman. additionally, who says that it ought to be a complicated race? for my section i don't think of THAT particularly of the government.

Not yet. It would take a few thousand years to get there.

That would require faster-then-light travel, which may not be possible.
