Okay folks, help me out with this one

Because I don't understand. I keep seeing articles about getting people to Mars. Mars is pretty much in the area when the sun explodes sooooo I'm not sure how moving people from one planet to another can help.

Is there something that I'm not understanding?

Thanks for any good advice you can provide 🙂

Dreams of certain groups of men to conquer and colonize.

If you look at Earth those certain groups have already conquered and colonized all possible places of Earth.

Odd are against man, not saying he never will - colonizing even the planets are the Moon that is closest to the earth.

They would have to conquer gravity

They would have to conquer oxygen

They would have to conquer the ability to grow food

They would have to conquer the ability to have drinkable water

They would have to conquer sustainable crafts that won't explode or break up

And considering the distance of the planets especially those outside of this solar system they would have to conquer fuel. The Moon is over 200,000 miles away.

@Learninglife9 Distance seems one problem the planet-colonising dreamers don't grasp.

Astronomically the Moon is very close but still about three days' travel away, at least by present standards.

Nor do the dreamers really suggest any sensible reason for "colonising" other bodies, nor address how any visiting team is supposed to return home. There are two possible, fairly credible reasons for visiting: scientific research beyond what is practical by remotely-controlled equipment, and less realistically, minerals mining.

Such mining brings its own problems of how to send thousands of tonnes of ore back to Earth, and bring them down safely. (Or tens of tonnes of the metals if it were possible to refine them there... which I doubt very much.)
