Where will they go?
How will they survive?

If any life at all is still on Earth in 4.5-billion years (..when the sun will expand into a red giant star) it will not possibly survive. The seas will turn into steam and the atmosphere will be blown completely away. By then humanity, if it still exists at all, had better have found another home somewhere else in the galaxy.

The Sun has about another 4.5 billion Earth years of life left. Will life still be around then or will it have been wiped out by humans or some other planetary phenomenom such as another ice age or an asteroid hit?
If we're still around, hopefully we would have developed some way of migrating to another planet. As the Sun runs out of fuel, it will expand into a red giant and engulf the orbits of Mercury and Venus and possibly Earth. If it doesn't engulf Earth, the heat from the Sun would have killed off all life anyway.
Sometime after expanding, the Sun will 'puff off' it's outer layers and become a white dwarf. With reduced gravitational effect, it's anyone's guess what happens to the rest of the solar system.

Any humans on earth certainly wouldn't survive. We won't be around thoug, we'll find a way to kill ourselves off long before then. If we survive somehow, I think there's a pretty good chance that by then we will be able to move at least part of our population.

When the sun enters the red giant state, I doubt humanity as we know it will even exist. If civilization continues relatively uninterrupted, we will have either killed off the human race or colonized the stars.
We've got 5 billion years to go; we're not exactly pressed for time.

I am sorry to have to tell you that it is too far in the future to be considered. Remember that we are talking about a time frame that is 2500 times as long as the time since the earliest hominids climbed down from the trees.
It is not impossible that our distant descendents will have developed methods we can't imagine and will have moved on by then. But they will not be us. We would not recognize them nor be able to communicate with them.
But most likely, the human race and most advanced life forms will die out over the next 3000 to 5000 years, and the earth will take on forms we know nothing about. Life is fleeting, and reality exists on a scale we cannot visualize or talk about.
I dreamed of being one among the lean, sinuous creatures, swimming for joy together in luminous fluid outside of time and space. I awoke with a sensation that an angel had been using the solar system for a toothbrush. Only half a wet dream.
Is a skeleton embarrassed because it’s naked? With all those teenage girls looking at it in science class?
The reasoning of ashes is not subject to intellectual rigor. Nor is it influenced by pain. It is only I, sitting here in sunlight, who shall feel and fear the loneliness of nights in the graveyard. For that is not to be me, but only the point of remembrance of me for a moment.
And our dreams flow away under the magnetism and gravity of the æternal pulling through holes in time.
Take one universe, dissolve thoroughly in water; stir vigorously…

FYI in about 3 billion years (most people don't know about this), andromeda will collide with the milky way.
So you won't have to worry about the sun destorying us after all...no. We're going to have to find an entirely new galaxy to occupy if we want to survive...

They must leave the solar system as when the sun goes super nova, it will envelop everything from here to Pluto.
Our atmosphere will be burned off so no air. Going underground will not work either as the temp will melt things. Everything. This planet will be destroyed.
You however will die of other causes long before that happens. You have a far greater chance of being killed by a drunk driver.

The Universe is endless.When our sun fires up, which will be millions of years from now and we haven't blown our selves up,we should have the technology to move on to somewhere else. (Hopefully). That is how we got here.

The sun is a great ball of fire. Global warming is caused by the depletion of the O-zone.
There's always underground away from the sun's harmful ray's

Humans are insignificant. We will go nowhere. We won't. Change the word "human" to "dinosaur" and re-enter ?.
