A single Being responsible for everything is a rather unbelievable claim. Of course people will believe the unbelievable if evidence and reasoning can warrant such a belief. I am an atheist because I have not found any evidence or reasoning that support such a belief. It actually gets worse because there is evidence and reasoning that supports all Gods/Goddeses spoken about throughout history being human creations, leaving only unknown Gods/Goddesses to ponder. The only reason to even ponder that is because of how many superstitious people believe in some sort of higher power. I sort of get why people do this. If we see a car, we know someone made it. If we see a house, we know someone made it. The problem is you cannot look at nature, something like a tree and automatically conclude someone made it. Learning how nature works through science and even personal experience demonstrates that not all complexity needs a who to make it. Natural process also form complexity, where an interesting note is if our intelligence is building cars and homes, why do natural formations stop at just our natural resources? If there is a higher intelligence, why not a city floating in our sky or space stations littered throughout our solar system? Then there is the matter of poor design of humans as well as all of the "natural" defects that can and do occur, such as extra limbs, missing limbs, deformities, etc that require our intelligence to fix if we can. Too much lines up with nature and natural formations rather than Intelligence. The thing about atheism is that it is not about having any answers, it's about the claims of theism failing their burden of proof. If my car won't start and you offer me Gremlins as the problem, I don't need to know why my car doesn't start to find the claim of Gremlins unbelievable and unsupported. If someone says I need new spark plugs, I already know spark plugs exist and are used for combustion and can at least accept that as a "possibility". But not believing in Gremlins doesn't mean I need an alternative explanation, just that I know what the problem is not.
