Firstly, there is no problem with atheism. As an atheist, it's a completely logical point of view that unless something is proven, there is no basis to believe it. Obviously this proof can range from mathematical proof to physical proof, the underlying requirement is that any proof is objectively verifiable by anyone or any group that would challenge the proposition.
The proposed existence of supernatural beings has been tested ad infinitum and has failed every time in any sort of repeatable, verifiable instance.
There is a huge test underway at the moment that is including the entire population of the world. If an interventionist god existed there would be clearly quantifiable evidence available that would indicate that segments of society that engage in prayer will be numerically less affected than societies whom do not pray.
Or even that any particular religion is what you like to call "blessed" and had the favor of the true god or gods.
Let's call this the Supreme test to prove that god exists or doesn't exist and once it's over, let's collate the results accept them and never speak of it again.
