Is that intelligent life is common therefore interstellar travel must be impossible. I do not believe human intelligence is any more mandated by evolution than the largest pterosaur, or land animals which no longer exist. Evolution is random.
It is far more anthrocentric to believe the universe demands our unique evolutionary achievement be repeated than to believe we are just another unique development from many random environmental factors just like every other life form on this planet.
The fact is most life forms radiate and develope new forms or they die. There are very few living fossils nearly unchanged for hundreds millions of years. Those that do exist are suited to environments that have been consistently available over that time frame. Even then evolution may be taking place at a molecular level. When size, shape, and intelligence are optimized things like immunity to disease and cancer become more significant survival advantages. It's not just human nature to explore and adapt, it is the nature of life itself.

- Maybe the answer is to use fewer resources...
- Interstellar travel is impossible, not just uneconomical
- False - Fusion sufficient
- Engineering Aliens - Think of Ayn Rand and Robert Heinlein
- FAST interstellar travel has a lot of hurdles for us at present
- We put our human limitations on any possible aliens.
