Maybe they will live under ground or travel to another planet.

Not absolutely a daft question - the solution would be to emigrate to other star systems.
But does this person not realise that without the sun, even if the Earth's atmosphere has not burned out with the demise of the sun, it will be frozen solid without the sun.
Temperatures will be around -270C - everything freezes, oxygen, nitrogen.
How would you replace the sun. You would have to create a sun. It would be far easier to develop technology to go somewhere else.
People seem not to have any idea of the scale of the sun. It is not just a fiery ball. It is 1.3 million times the size of the earth. It is 99.9% of the mass of the Solar System. The rest of the Solar System - planets, moons, asteroids, comets, meteoroids - are just debris left over from the birth of the sun. The sun is everything. It is irreplaceable

As the sun begins to burn out, it will actually expand, fully engulfing Mercury and Venus, and coming very close to Earth. At this point, the intense solar wind will strip away the Earth's atmosphere and the intense solar heat will burn everything on the surface to a crisp. Might technology be advanced enough to survive this? Well, we've got about 2 billion years until that point, and a lot can happen in that time. Most likely, Earth will have been hit by several large asteroids by then, effectively wiping out life as we know it (according to statistics anyway). So I'm not so sure the human race will make it that far to find out what happens.

Humans will have ceased to exist long before the Sun burns out. Life has been on this planet for about 3.5 billion years. None of those early life forms still exists and along the way to evolving into the myriad of forms existing today, more than 99% of species became extinct. The ancestors of humans from just two million years ago are all extinct. Modern humans have been around for, perhaps, 200,000 years. We won't be here in 2 billion years and it is unlikely that what we have evolved into will be here either. Even if we colonise other planets, humans as we know them today will not exist in 2 billion years.
The earth will still be there and there will be life on it, perhaps intelligent life, but it won't be us.

No, the earth will either be burnt up to nothing, literally not exist, or we will be sent off into deep space. With no sun or orbit. That won't be good for anybody. No, humans had better find a way off this rock before that happens. Or it's going to be a very bad day to plan a vacation.

No, we will cease to exist. The good news is that the sun is just a young fella and has enough energy to last a few billion years more.

The earth will vaporize as the sun turns to a red giant and probably grows to the orbit of mars.

the sun has enough energy to last for about 5 billion years!!!
