if you can't empirically prove God doesn't exist, why should I be an atheist?
You've got it backwards. The atheist bears no burden of proof because he is making no claim to prove. When it comes to claims about theism, the theist is the only one who has a burden of proof, and if he cannot make his claim, reason resides with the atheist.
And I will add...
Most atheists will not close the door on the possibility of a god existing at 100%. They will leave open the possibility that there may be a god, or gods. But the atheist is NOT making the claim that gods do not exist, they are responding to the original claim that there is a god, or gods in existence.
I've written this scenario before, but I will do it again.
Long ago, someone made a positive claim regarding the existence of a god. That is how it started, not the other way around. Imagine someone claiming the non-existence of something, before that something had even been defined or imagined? Silly, yes. So there was never a time before the idea of gods where someone stated there were no gods. Once the first god claim came into human communication and ideas, the first atheist was born. The first skeptic, if you will.
There were likely many people who truly doubted the existence of Zeus, despite the very strong evidence in lightning bolts coming from the skies when he was angry. We now know, of course, that there never was a god throwing lightning bolts in anger. We know exactly what causes lightning.
The same is true with all gods ever invented so far. Not one of them has ever been shown to actually exist. Every single one of them are invisible, and can only be known through the process of that particular religion, or mythology that propped it up in the first place. And what's even more damaging, especially for YHWH, is that those rituals and processes to "know God", have dramatically changed over the centuries. Isn't that odd? How many sects of Christianity are there, and how many ways are there to know god through the rituals of that particular sect? And how many of them claim to be correct in their approach? All of them claim to be correct.
I know this was a complete waste of time typing this up for someone as deeply deluded as you appear to be, but I had to do it for those who lurk, and those who are questioning their beliefs right now. When they read these replies, they will begin to shed the delusions, and find that there is a perfectly fine way to live out our lives, with no need for god beliefs whatsoever.
