Other solutions might be going to Jupiter's two moons Europa and Io. There is a problem to handle if the humanity moves to them as well. We may can protect ourselves from the lethal radiation in the universe, but I think think we will respond well to the immense gravitational pulls from Jupiter.

The problem isn't whether the sun will swallow the earth as earth will be uninhabitable long before we get swallowed in about 5 billion years.
In about 1 billion years it will have expanded enough to boil the oceans but even before then solar flares will potentially be swallowing us and well before then temperature increases will make life a lot more challenging.

Hawking in my opinion was right if we are moving off this planet by the end of this century mankind is doomed.

One option might be to leave the solar system. They are finding a lot of exoplanets orbiting within the goldilock zone of their stars. But to achieve that the mankind need to develop spacecrafts that can reach ludicrous speed.

The search for exoplanets is really interesting

The short answer is yes we will have to leave the solar system but I still think our best bet is a leapfrog process to get us out rather than hope to do it from earth.

The use of space stations can be better than using "dead" planets. We have the international space station now. In a few million years the humanity might have even better launching pads orbiting the sun that can be used for such. But it depends on if the humanity still exist at that time. It might be another species of the genome Homo
around when it's time to leave this planet

I have just read something interesting. The Homo Sapiens might be older than we thought, They have found a fossil of Homo Sapiens that is about 300 000 years old. It was assumed we were "only" 200 000 years old. In deep time, 300 000 years old is not that old. Still very amused and annoyed that some religious people think this planet is only 6 000 years old.

I would be surprised if this planet will be habitable in 300,000 years so I suspect we are the end of the evolutionary line.
As for the idiosyncrasies of religion, there is nothing more amusing than discussing paleontology with the fanatics.

We will probably cause our extinction even if there are other potential events that can wipe us out. The first that comes to my mind is Yellowstone volcano.

It's even more fun to discuss genetics with religious people.

Yeah we have the Taupo volcano here that last erupted in the 1800s, if it was to go off it would wipe out the central North Island.
Fortunately it isn't showing too many signs of life.

You live in a geological active part of the world. Indonesia has its fair share of big volcanoes that can wreak havoc on the South Pacific and some of them can even cause global devastation. The Tambora eruption in 1815 caused crop failure in both the US and in Europe. It supposed to be largest recorded eruption. The Krakatoa eruption was pretty big too and it also contributed to the scientific field volcanology. A Dutch geologist witnessed the eruption. Krakatoa blow up en entire island between Sumatra and Java.

The Santorini/Thera eruption was probably bigger than Tambora, it devastated
the Minoan civilization. There are other super volcanoes around the world. Toba is also situated in Indonesia, the last eruption occurred 48 000 years ago and almost caused the extinction of the humanity according to genetics and paleontology. Vesuvius is a famous strato volcano outside Naples and it's a part of a super volcano, the coast line of the bay of Naples is a part of the caldera. If that one goes, the entire Europe goes.

Iceland has a few volcanoes that can cause major devastation. Laki erupted in 1783 and caused crop failure and famine in Iceland and Europe, it probably contributed to the French revolution.

Another natural disaster that can put humanity to the brink of extinction is something similar or even worse than the Spanish Flu. But I doubt a pandemic can cause our extinction but it can cause a major reduction of the population

Well if we are lucky the Apophis asteroid will sort out all the issues in 50 years.
