Right now we face several life ending events, the poles might flip, the megnetic field might collaps, the sun might go nova, we could get hit by a comit, the moon could explode, etc.
These are all real possibilities and surely one day one of them will come to pass and we will all be no more.

Depends what you mean by poles might flip. If you mean the magnetic poles flipping, well they posit that may happen relatively soon. They also don't think it'll have much of an impact or any impact at all on life. It's happened many times before.
Magnetic field collapse...I don't think that's too likely to be honest.
The sun is guaranteed to go nova...but not for another 4 billion years or so...
Hit by a comet, entirely possible. I'd be more worried about an asteroid though.
Moon exploding, no mechanism I know of that would cause that except for a massive impact from an asteroid or similar body.
Honestly, I'd be more worried about a supernova in our stellar neighbourhood, as that'd be guaranteed to wipe out all life. Or a gamma-ray burst nearby that was aimed in precisely the wrong direction, thus also sterilizing the Earth.
