So instead of taking a step forward and proving god, this argument takes many steps back and say everything is uncertain, therefore god is as valid as everything else? If you were to take that position then you have to accept every possibility because you're dismissing the idea of plausibility and gradations of plausibility.
For solipsism, if you're truly a brain in a vat, why not just stop eating? That wouldn't affect you, right? You wouldn't die because you stop imagining that you're eating, you'd still receive whatever sustenance it is that you've been receiving ... ? So it's testable, except you have to die to test it. Interesting, and what's the point of this argument? (This is why philosophy is not my cup of tea)
As for consciousness and souls and stuff, look into neuroscience for some very enlightening cases on how consciousness works in the brain. Mainly split brain. For all intents and purposes, 2 consciousness in one body.
