You have to think outside the box re space travel. Even close to light speed is not that useful considering the vast distances.
It's been theorized that a craft could be enveloped in it's own piece of space / time, effectively enabling it to travel beyond light speed. That's the fundamental theory of warp drive - you warp time & space around the craft.
Another popular theory is travelling in a series of jumps by bending time and space, as it's considered a dimensional fabric.

I studied astrophysics for a bit, but that was 25 years ago!
Some laws stand firm though - hence thinking outside the box.
For example, a craft will never match or exceed the speed of light. You could get close, but that's it.
Reason being.
A craft is mass, light is pure energy.
As you accelerate mass, it gains more effective mass. As the craft accelerates, it gets heavier requiring a more powerful engine to push it faster, as it gets faster, it gets heavier requiring a more powerful engine - ad infinitum! Therefore, you'd need an engine of infinite power, which to our current knowledge is not possible, although it has been theorized using an ion drive.
With the other methods you are kind of cheating. If you warp time and space around an object, it's no longer a mass moving through space. It's kinda like space (or energy) moving through space.
That along with bending the fabric of space, have been investigated many times and never been really discounted as being plausible.

Anyways, it's incredibly naieve to think that we are either alone, or other life (if found) would be primitive.
You just have to look up at the number of stars. When a sun is born, planets are a by product. There could be millions of planets in the goldilocks zone out there.
Not only that, many could be hundreds or thousands of years ahead of us in technology.
Look how things changed here in just a 100 years or so.
The first successful powered flight was circa 1903 - look at us now with supersonic jets!
When I was a teenager, you'd not even comprehend things like mobile phones & mps3 players etc.
Imagine a civilisation thousands of years ahead of us and what they may have developed!

All the talk at the moment, at least in the news and documentaries, is about finding life of a very primitive sort but that is considering only planets and moons in our own solar system.
There is more than a distinct possibility, in fact I believe it is a certainty, that there is advanced life somewhere much further afield and it is fascinating to consider what form those beings might take.
Science fiction films/TV programmes have even suggested that they might be of pure energy without any corporeal form, but I find that difficult to even imagine.
