Earth-like? I'd believe it when they get there. Here's the travel time:

-Current rocket technology (if a large enough one could be built): 120,000mph.
25,000 years to get there.

-Project Orion 10,000 ton class ship: 80% speed of light peak speed.
14 years.

We can't even get humans to Mars, never mined to another solar system.
We found out, there is no other life in our solar system, not even a lousy bacteria, so now it's a new flight of imagination , maybe some thing exist in another solar system.
