Just by changing the language you deceive yourself about the nature of what you call facts. There is nothing absolute about what may happen about four billion years from now.
Don't grasp at straws, Jan. I was reading about a similar objection by flat Earthers this morning. Of course nothing absolute per se but (sans catastrophic cosmic events like pulsar blasts or rogue objects) the Sun will expand in a matter of billions of years because every star's lifespan is largely determined by mass. People and dogs of the same size don't have the same longevity but stars do.
So, if humans don't devise some extraordinary technology, biology on the Earth's surface is well into its old age, humans or not. Most of us hope to leave some legacy rather than just be a blip in a night, and I hope that the Earth will have a legacy beyond its fate of being engulfed by the Sun. To what end, people ask?
That depends on whether one believes that the Earth and its life are unique and alone, or if life on other worlds will gradually spread out as humans did on the Earth. Is it not a good thing that ancient cultures were keen to make a legacy, leaving artefacts and writings that helped moderns to better understand what had happened? Are we like the first humans to leave Africa,

My point has been, and continues to be, that "we" is a relative term. "We" can refer to all of humanity on the Earth in the biosphere, or it can refer to smaller groups. However, when it comes to the practicalities, the "we" becomes more tenuous. Billions of people and animals are not being sent into space. A very select few - or perhaps only AI plus the data and DNA need to rebuild - will go to the stars. Any people sent on long haul space trips will need to be massively genetically engineered, perhaps to a point where they could not live on Earth without survival gear.
Thus, in a matter of thousands of years most humans and their lines will be effectively dead - that is locked in unless scientists learn to control the weather. The space program is about preserving something
, not everything. Alas, God is planning to use Noah's ark as a prop in the upcoming Big Armageddon Show, so it's unavailable for hire to save all the people and critters ...
Note that the "nincompoops" are the ones most likely to survive the upcoming firestorms - at our expense. Haven't you noticed? Survival of the fittest translates to survival of the wealthiest in humans. So right wing climate denialist politicians are being less stupid than they are being selfish - effectively cutting loose their children and grandchildren. It amazes me that so many young people still vote for conservative politicians who are clearly selling out the young.
