You do realise that you're wrong on several accounts and that Kalam argument doesn't work, right?
I will criticise a couple of points briefly. Firstly, if time of universe's existence is finite ('time' is not a proper word here, which you seem to have ignored) then there's no reason that there has to be a point that nothing existed. Secondly, I can also say that that something "immaterial, personal, self existent*, 'outside' of time*, and logically necessary" (* whatever that means) couldn't in its timeline exist without a cause, as, because its time also cannot be infinite, it couldn't "reason itself into existence", and there is something else that is "immaterial*, personal, self existent, "outside" of "outside" of time, and logically necessary". Also, requiring that "logically necessary" thing to "exist 'outside' of time", be "immaterial", "personal", "self existent" because "universe can't decide to reason itself into existence" is jumping to conclusions.
Also, are computers "personal" (as in, what you mean by the word "personal")? Because they somehow can vary their output depending on the input.
Also, the Kalam argument is irrelevant to the topic.
