Apparently you discriminate in your choice of philosophers. Krauss seems to regard himself as something of a philosopher. And I must say, your defense of Krauss is strange in light of the following. Krauss seems dedicated to erasing the notion of God from all the young skulls full of mush.
A quote from Krauss in the Atlantic magazine " If the multiverse really exists, then you could have an infinite object—infinite in time and space as opposed to our universe, which is finite. That may beg the question as to where the multiverse came from, but if it’s infinite, it’s infinite. You might not be able to answer that final question, and I try to be honest about that in the book. But if you can show how a set of physical mechanisms can bring about our universe, that itself is an amazing thing and it’s worth celebrating. I don’t ever claim to resolve that infinite regress of why-why-why-why-why; as far as I’m concerned it’s turtles all the way down. The multiverse could explain it by being eternal, in the same way that God explains it by being eternal, but there’s a huge difference: the multiverse is well motivated and God is just an invention of lazy minds.

One assumes that even Baptists are included among those " lazy minds " which have " invented " the notion of God. What he is saying here is that God is nothing more than an invention to fill in the " gap " of explantion needed to make our existence intelligible. Strange that you should defend on who has so high a disregard believers of all of all persuasions. And while you may dislike Feser because of his polemics, at least he is defending the notion of God, even if he is not of your faith.
It is difficult to see how you could ever reach Krauss, or those who follow him, by Sola Scriptora. He would just laugh at you, in fact he already has. The only way to reach him is through solid philosophical argumentation. He may not be reached by that, but some of those who have listened to him may.
Oh, by the way, you omitted the philosophical definition of " nothing, " which is the absence of anything, even " empty space." ( Courtesy of Thomas Aquinas )
