It's incredibly unlikely that there is not another planet with life on it out there. But we're unlikely to ever leave our galaxy. We may never get out of our solar system even. Humans' aren't really designed for space travel. We're too big. Short lived, We need gravity, air, water, a narrow temperature range, diverse foods, and lots of space. We don't care well in radiation, and we're nuts. It's more likely that we'll creat AI life forms to do the exploring for us.
@Tastyfrzz You're right. In addition, we're not even a type-1 civilization yet. Space exploration, realistically, isn't on our calendar in the next future.
