Fair points. I will personally take the time to address as much of what you say here once I have the time, Deese. I just want to state one thing though regarding Platinga is that he's not known for popularizing any first cause argument.* So when I mentioned him, I didn't mean to treat him individualistically but rather as part of a group of theistic philosophers known as "theistic personalists". They tend to believe many similar things about God's nature though, and I'm pretty sure he does believe that the first cause is eternal (well, I'd be surprised if he didn't).
*He is known, however for his Modal Ontological Argument obviously.
