We may NEVER find proof of extraterrestrial life. Space is just too damb big. The Milky Way might have millions of civiliazations and we might never find proof of their radio signals due to how much a signal can degrade over time and distance.
Even if we did manage to intercept a signal, locking on to it and tracking it over time wouldn't be easy (think about how fast the earth rotates, rotates around the sun, and the solar system rotates around the galaxy). The speeds are mind numbing.
Now imagine we do figure out how to thwart Einstein. The distances are still crazy. If we do find an advanced civilization, what are the odds that they are still around by the time we get there?
