The universe is playing Russian roulette with us

Russian roulette is a game of chance, in which a bullet is put in a revolver, then the cylinder is spinned, the muzzle is put against the head and the trigger is pulled. 

You have 1/6 chances to die.The same is happening in life: when you cross the street, it is x% chance to be hit by a car, when you fly a plane it is y% chance to crash, when you go to a terrace in Paris it is z% chance to be shot. I don't count here millions of deadly viruses,bacteria's,diseases,radiations,chemicals,human killers that could end our life.
We live our lives by ignoring this. It is like universe is playing Russian roulette behind our back and we are not aware.
Sometimes, life makes us to turn around and face the revolver pointed at us with cylinder spinning.
Then we are scared  because of uncertainty: we will have x% chances to live and (100-x)% to die.
It is like facing a guy with a weapon in the hand or a wild beast preparing to charge.
Our fight or flight system is torn apart by the conflicting decisions.
If they attack  you will focus on defending yourself and forget about fear, but they wait, and you are uncertain and tense.
We don't like uncertainty and because of that we used gods as explanation when we didn't understood natural phenomena.
Uncertainty produces fear, and because of that we ignore it or we search any explanation plausible.
