Yeah, there is a series, which at any time may begin with a God who has existed infinitely. Anyway, that would be when he made our bodies. Our essences are co-eternal. When it says beginning and the end, I don't know what that means, since I certainly don't think he is going to end us at some point. I will look into it, but if you are basing your entire criticism on a rhetorical phrase, I think you know the argument is weak.
