Honest Qestion why do people care about space exploring other planets ect? aside from the The US and other governments getting to spend money I just really don't see the appeal.
For most of human history, if you didn't like the rules of the society in which you lived, you could go off and start your own society somewhere else (often with blackjack, and hookers). And if society didn't like you, instead of killing you or putting you in a cage for the rest of your life, they could exile you to a far-away land where they no longer had to put up with your shit.
For the past 100 years or so, we haven't had any distant lands we can settle, or to which we can exile undesirables—pretty much the entire livable surface of the Earth is claimed by one nation or another, including the oceans (Seasteading sadly isn't practical). I overwhelmingly feel this is bad for mankind.
That old adage, "buy land, because they aren't making any more of it," stops being true once we can practically travel to the stars. Then, instead of having your economic destiny pre-determined by the choices your ancestors made (where they settled, what property they purchased, what they willed to their progeny), we can once again become free men with our future completely in our own hands. You and I can't (yet) afford starships, but neither could our ancestors afford their own boat, and now there's harbors full of weekend sailors, airports with privately-owned single-engine piston planes, etc.
We need an escape valve from the tyrannical governments that keep us captive.
We need a place to try out different societal structures, far enough away that the failed experiments don't piss off the neighbors too terribly.
We need to kindle man's innate urge to tame the harsh frontier and build something from nothing.
Barring a nuclear war that depopulates entire continents, IMO the best alternative seems to be to settle other planets.
