Theist trope: "Is life just a game?", what's the best way to rerpond?

[robvalue]

This is backwards.

Life is a game to most religious people, not to atheists. Life is "just a test". What more of a game could it be? It reduces existence to some sort of perverse sport with a celestial umpire grading people.

To your average sceptic atheist, life is the likely entirety of existence, and so has far more value and reason to be taken seriously at every turn.

I was discussing with a friend recently, and we came to the conclusion that life would seem like a game to a psycopath; someone who is incapable of caring about anything, not even themselves.
