Does it matter if there exist a "God"?

I'm refering to the typical concept of "God" that religions preach. I mean, a God that is somewhere watching over us, listening to the praying of the people but doing nothing about it, seemingly. A "God" that is waiting for the end of the times to reward their slaves... I mean, people who obey him, and also to punish mercilessly the people who didn’t put on their knees and obey him word by word. Haha. 

Jokes aside and in all seriousness. Is it worth the endless debates between atheists and religious people? What religious people get if atheists accept that there is a God? Are they getting a salary increase if they do so?

To me this is pure fkn ego, either from atheists or religious people competing to convince others about their position. Although, I've got to admit religious people are more fkn obnoxious because I've never met an atheist trying to convince me there is no God.

What do you think, dear atheist? Have you ever thought about what it would happen if you accept that God exists? I tell you what would happen. Nothing. It's worthless. So, next time a religious guy tells you that there is a God, just reply "yes, I agree" and turn back to your duties. Be happy. 

Sound advice but not as much fun as  a bit of banter trading.

It's rather like advising  the fecund to not bother about sex.

Nonetheless, if there is a GOD I'm guessing that it is not as stupid as theists make it out to be.

And takes little interest in the machinations of human society.

Perhaps smiling occasionally when it gets the time to see us do our stuff.

And when we die, it doesn't notice the difference.

Eh, I think 'sometimes it can be ego, by people who say they are Christian or say they are Atheist,

Other times, I think they 'value what they see as the 'truth,

Or what they see as lives worth living,

Lifestyles that are good for humans,

And they want to 'help other people.

God doing 'nothing? Slaves?

Eh, depends on your perspective I suppose,

Or one's hopes.

I think I'd be a better person, and more drawn to good, if I believed God existed,

But eh, I'm a former believer.

And even without belief in God, I see a lot of game theory in the Bible, and various other religious texts.

When the end of the world comes and your Gods remain silent, do not turn to Meow. Meow offered you his/her hand, but you rejected it then. Ameow.

Atheists are just as bad as criminals.

More by way of benefits, but that should count heavily as well, but few look at it that way. Their loss.

How does one successfully argue a negative? Some atheists are smart enough to know that, as you concluded.
