It’ll swell into a red giant, whose outer layers will engulf Mercury and Venus and likely reach the Earth. Life on Earth will end. If the sun were more massive – estimates vary, but at least several times more massive – it would explode as a supernova.

What will happen in the next 5 billion years?
Beginning around 5 billion years from now, the Sun will expand, becoming a swollen star called a red giant. By 7.5 billion years in the future, its surface will be past where Earth’s orbit is now. So the expanding Sun will engulf, and destroy, the Earth. It’s been suggested that Earth might escape.

five billion yearsIt still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
Why did humans almost go extinct?
Genetic bottleneck theory The Youngest Toba eruption has been linked to a genetic bottleneck in human evolution about 70,000 years ago, which may have resulted from a severe reduction in the size of the total human population due to the effects of the eruption on the global climate.
