To Boersun,
Don't give up.
There are many ways humans might get to the stars.
Some ideas to ponder.
1 Geometric progression of energy.
In 10,000 years time if the 'geometric progression of energy' holds we will be producing enough energy to probe the nature of space itself, we could feasibly create wormholes between stars and collapse them at will, other stuff might become possible too once we know the true nature of space.
2 Probability field
If it is true that you only exist where you do in spacetime because your probability field has a high peak in that particular area of spacetime simply adjust this to somewhere else like Eridani and 'puff' your gone teleported from one side to the other like a quantum leaping electron.
3 Time dilation
Speed up at a modest 10/m/s and you will get their eventually taking advantage of relativity and not aging very fast. Sure back on Earth maybe 10,000 years has passed. But stuff them you are a brave warrior and can live without all that sentimental nonsense as you carry the seed of humanity to the stars.
Unless of course in that 10,000 years the earth humans have found a way to fold spacetime and arrived before you taking up the good real estate. Then it's
war relativity old style.
4 Rely on Alien Ancient Technology to do it for you. Admittedly this is the laziest of my 4 suggestions but weirdly crops up in many sci-fi stories like Babylon 5 or Stargate.
Hope this helps you Boersun.
