That's where we are--but the universe is 14 billion years old, and there are many, many planets out there much older than ours; some several times older. It should only take a few millenia for any truly successful life in our galaxy to colonize the whole thing: less than a cosmic eyeblink.

- krschultz 16y agoYea but that point, you are getting around faster than the speed of light. If you can move faster than the speed of light, why would you use radio waves for anything? What if their entire communication/transportation happens in some manner we can't comprehend. Imagine trying to show an iPad videochatting someone else to Da Vinci. It would be black magic with so many layers of technology that he couldn't comprehend - and he was a smart guy. So in a few hundred years we've blown everything we thought we knew away. Who knows what physics and technology we will have in a few thousand years?
