Vlad,
Yes, no reason to believe what?
After all these years you still have no idea how the burden of proof works have you. It’s not for the atheist to explain every type of god definition there is before deciding not to believe in any of them. If someone want to assert as true his claim “god” then it’s
his job to define and then to justify it.
I’m an ignostic because all the definitions of gods I’m aware of are incoherent or white noise (“the ultimate” for example – the ultimate
what exactly?), and I’m an atheist because I can falsify all the justifying arguments I’m aware of for the existence of gods, whatever their definitions happen to be. My position may change if ever a coherent definition and a logically sound justifying argument come to my attention, but so far at least neither of those things have happened.
