Not a theist? Could've fooled me with all that godspeak.
I agree, but the truth is the more you know the more uncertenty you have in your life.
So you at certain point can prove or disprove that deity exists or not exists, and it's not really related to their actual existance, it more related with your mood.
If you are a atheist soldier and you will fight to death with all who believe - when this is you choice really, its not a question is it that true or false, it's just your way of life.
Wherefor it is impossible to discusss your believes with you, - you will just fight to the end or die with honor (of course where is no honor in calling someone non-native english languadge to your benefits) but i guess you are a young soldier and you will learn it some day.
