One can be forgiven for not having stumbled across these arguments before. We all had to read them for the first time at some point. But I'll just say that this is well-travelled territory.
The fact is there is no reason to state god does or doesn't exist. There are more important things to think about. Things that actually make a difference.
According to the bible, the consequences for non-believers are very dire. If the bible is true, then this is a very important thing to think about.
Weak agnostic or strong atheist, we're all going to hell.
I contend that there's little difference between a weak agnostic or a strong atheist. If you're not scared of hell, then you're living your life as if you believe that God doesn't exist.
As in most things in life, it's what you do that matters, not what you say.
You are wrong! In fact, the water does not exist, the glass does not exist. You do not exist.
Could this be? No, you say, I have proof that the water exists: "I can drink it". Not really. You think you can drink it. But you are not there. The water is not there. Maybe you are in the matrix.
Just like that, any kind of rational discussion is impossible. "Hard water believing", believing that the water exists just because you think you can drink it, is not rational - after all, it could not exist.
Should science work like this? Should science explain, when stating any theory, that it could be that all stated facts are maybe not real? Obviously not. Science only cares about falsifiable theories: theories which can be disproved. The rest, from the point of view of science, does not exist.
From the point of view of science, the water exists and god does not exist. Neither do the golden unicorn, or the green monster. God believers, and water deniers, when using those believes in the realm science, are making science a disservice, since they are allowing for non-rational conversation - and thus destroying any kind of rational discourse.
However... the politically sensible position to take in these sorts of discussions is ignosticism - the idea that you can't know because you're ignorant of what the terms are. Unless you can define what god is you can't state whether or not there is evidence for his/she/its existence. Most religious people don't like defining their god, so they leave you alone. :)
