Someone said we’ve never sent a probe out of our solar system. I replied to say we have and I’m being obtuse?
His point was interstellar travel.
Voyager is hardly interstellar travel. It takes light just 22 hours to reach it and its been travelling for 30 years. Some scientists may say its left the solar system, others disagree and say its in a supposed ort cloud and still affected by the Suns gravity.
In any case I agree with his point that interstellar travel at great speed by humans or other lifeforms is next to impossible.
