not millions of years, as the previous answers say. try about five billion years from now. at that time, the sun will have used up its supply of hydrogen fuel. it will try to burn off the helium that now fills its core, and expend so much energy in the process that its outer layers will expand beyond the orbits of mercury and venus, and making earth's surface semi-molten (if it doesn't destroy the planet). it will thus become a red giant. as it slowly cools and fades, it will shrink to become a white dwarf, and finally die out as a black dwarf. hopefully before then, we'll have long since been gone, if we haven't destroyed each other by then.

In several million years. The sun is about halfway through its lifespan. It is older than most stars but again, it will take several million years for it to burn up. Well it'll either burn out and collapse or grow so big and unstable that it will explode or implode. We will either be extinct or all one race of super humans. Our technology would increase the human lifespan by several years. We would probably estimate when the sun would give out and there would be a lot of chaos. But I think that there won't be any humans around when the sun goes out. Its gonna take awhile.

it is estimated that in 4500000000 years the sun will go nova, that is explode, and destroy the earth.
primitive hominids have been around for 6 million year, our species (homo sapience) for 200000 years.
in the time remain until the sun explodes we would have evolved maybe 10000 times, each time changing into a new species.
That is if we don't start increasing the pace of evolution, as is very likely to happen in the next century or so, and evolve into super beings.

of course the sun will go out one day. it will take many millions of years though. if the human race survives up to that time we will die due to the lack of sun.i can just imagine that we would have discovered many other planets and also live in them.
