The funny thing is, there is no proof that it is habitable. It might be, but might not. Spending all of our fortunes and planning to go in about 2 years, on a manned mission to a planet that we don't know anything about, well, it's kind of dumb.
Secondly, it seems people ignored this:

There's much closer planets that could also be habitable.
Also, agentmax, that's the first thing that i've seen you post that actually makes sense. If we plan on reaching a planet light years away, it's quite possible that we would need to start a civilization within the ship, and if the first generation can't reach the planet in time, their children/grandchildren might.
