Interstellar travel is entirely in the realm of possibility for the future. I'd even call it likely. We'll have to wait a few centuries probably, but we'll do it unless we get derailed or extinct. On the other hand there are theories around how many alien civilizations there are and there are probably not many if at all. Basically we are "early" and there is probably no other civilization in the milky way.
