In 5bn years humans will not be humans anymore. The sun would be a Giant and thus the earth would not be there as the sun would occupy that space. Neptune and Pluto would have collided along with other objects colliding, possibly the earth and a comet. In fact in just 1bn years the earth would not be habitable.

In just 1 bn years. Lol. We are so indoctrinated by these big numbers that it feels like it's around the corner. Our written history is just around 7000 years old. We have enough time.

The "in just" is relative to stars and planets natural lifetimes.  Its been 4.5bn years for the sun already.
