Ah Sweetpea. Has no one schooled you on atheism yet? Well, let's get on with it. It's not your job to prove a negative. How even would you? Prove to me that unicorns don't exist. (I'm being super annoying dismissive atheist now. Of course unicorns don't exist and HOW DARE YOU.) But for real. It's not your job to "prove" that god doesn't exist. How would you even going about proving a negative? That's not a thing. The best you can do is show that there is no evidence to show the existence of God, but GOOD LUCK. The existence for god, to believers, is that he speaks to them and tells them the things they think anyway. Wooo! So, against the fact that "God" speaks with their own voice....good luck. That's all. Good luck.
Of course no one can prove or disprove the distance of God. The best we can do in this scientific age is debunk myth associated with divine claims with research and evidence.
A good way to begin is to analyse claims in holy texts. We see reality is starkly different.
1. Historically there no way Jews existed at the time of ancient Egyptians. That is a fact. Historically we see inaccurate claims.
2. Physics: cosmology shows a physical world totally different from claims in these holy texts, people living to 200 years, raining for 40 days to flood the entire earth, a man living in a whale, divine intervention breaks the laws of physics.
Ignorance is being lifted one mind at a time. That is all we can do based on evidence. Once provided with facts, it's up to us to decide what to do with it.
