so let's imagine that in 100 years we somehow reduce the time it takes to reach Mars form 230 days to just a week. 7 short days, traveling at about 1/800th the speed of light.
it would still take 3,340 years to reach Proxima Centauri, the nearest star. and a full 16,000 years to get to reach the closest known earth-like planet.
do you see the problem?

It's easily possible that any other life in the universe has discovered a way to travel that we have not. Other life (especially a species that may be a hundred times older than humans) is not necessarily held down by what we see as possible/impossible. We shouldn't assume that they can't do something just because we can't. Does that make sense?
