There are people living in space stations right now? Are you saying rockets are fake or do you mean that we don't have any permanent habitats on other planets?
They are not living in space, they are temporary visitors on an unstable structure that requires constant resupply from Earth, absent of which they will all die and the structure falls back to Earth and is destroyed. Even with indefinite resupply, astronauts have to return to Earth for health reasons, because our bodies did not evolve / were not designed for space. Astronauts get irradiated and lose reproductive fertility.
I can't really find where your line for "space travel" is. Humans on earth need resupply from other parts of earth, the bases on Antarctica are about equally as unhospitable towards humans, not to mention cruise ships where some people live aboard for years at a time.
Heck, my own house is an unsustainable habitat that requires constant resupply.
