We will have the collision with Andromeda Galaxy a few billion years before, so don't worry :)
Colliding with andromeda won’t do anything. Galaxies are almost all empty space.
We'll see.
No. We will not.
You won't mortal
What if some alien civilization is watching the whole thing and taking bets
If they live for billions of years, I’d imagine our human evolution has happened so quickly to them, that they wouldn’t even realize we were here.
I imagine that they perceive time like we do, they’re just very patient.
Imagine if the last thing we saw before colliding with another planet was another alien race on that planet looking hopelessly right back at us.
Can't it mess up our nice solar system if other large objects come even remotely close?

There are actually a bunch of stars that will pass by very close to the solar system in the far future (tens of thousands of years) and they could possibly increase the number of asteroid and comet impacts drastically.
It could set if a wave of supernovas, though, which would be bad for anything living in either galaxy. AFAIK our understanding of the process isn't good enough to know.
But it will be beautiful to watch!!
Neat there's even a video: https://en.wikipedia.org/wiki/Andromeda%E2%80%93Milky_Way_collision
5 is a few
Nah, we will build a stellar engine prior and move ourselves wherever we want. We will have colonized all the Milky Way and most of Andromeda. It'll be like a brother and sister finally meeting near the washer.
The sun is also slowly increasing in energy output. Earth will be too hot for complex life to exist in about 800 million years.
Space is so vast that the Earth and Solar System will survive.
