Exactly.
To say it's unfeasible for extraterrestrials to travel the vast space between us and them is an assumption solely based on our current (comparatively primitive) understanding of the physics involved.
When you think of all the remarkable technological advances we've made just in the last hundred years - imagine what a civilization that's managed to survive a few million years has possibly developed.
To paraphrase a favorite line from 'Contact' - if there wasn't any other intelligent life out there...what a big waste of space.
