We're actually one step closer to get in contact with possible lifeforms in outer space: Voyager 1 is about to leave our solar system these days. (Ok, it will probably need a million years to reach any other system which could contain life supporting planets, but at least now we have the proof that we can build technology to travel to outer space )

Actually the fuel should not be the problem, because the voyage is in vacuum which means there is no resistance that slows down the vessel once it has reached it's traveling speed. I just recently realized and thought about the fun fact that basically in all Sci-Fi movies you see the spaceships with their engines on while that wouldn't be necessary unless they want to change speed or direction.

Achieving a reasonable speed for interstellar travel is much more of a problem.

200 years ago nobody thought it was possible to travel 50 mph without dying.. In 2004 the X-43 reached 7000 mph.
There are animals who are faster than 50mph with just their muscle force. People would have just needed to look at these to know that you don't die at that speed. A space shuttle when reaching orbital speed has about 7700 m/s which is about 17000 mph. It's not the speed that is dangerous, but the acceleration.
