First of all, we do not have "zero evidence about the structure or faculties that reality itself has". Everything we experience is evidence of physical reality. We observe that events in physical reality have beginnings, but it is quite another thing to assume that physical reality itself must have had a beginning. The assumption becomes absurd when you start attributing the beginning of physical reality to a being like us that thinks and plans things. After all, we also have "beginnings", so why should something like us have been necessary to bring physical reality into existence? There are less absurd possibilities.Why does it seem impossible? We have zero evidence about the structure or faculties that Reality itself has. We know nothing about whether or not it had a beginning. If it had a beginning, then by necessity it must have been created in some way. Whether that is self-generation or creation via some divine protocol that exceeds the grasp of mere mortal beings is ultimately irrelevant.
Your position seems to boil down to an argument from ignorance. You do not have to consider every possibility as equally plausible. One reasonable possibility is that physical reality just always existed and did not need an external agency to bring it into existence. To assume otherwise is to invite an infinite regression of external agencies until you arbitrarily decide that one of them is the ground level--"turtles all the way down".Does this sound arcane and wholly beyond belief? Well, since I am working from a position of almost infinite ignorance and the "Real" might well be infinite I am not prepared to discount possibilities simply because they seem to defy my capability to understand properly.
