In the end, it's simply a recursive argument: even if we actually live in a technologically created universe, in the end there will be still a uncreated universe, whose existence is as mysterious as ever. So, why don't we just cut to the chase and say that this is the uncreated universe? My feeling is that Occam's razor could be invoked in this instance and do not lose any significant information.
Yes. Let's consider, for example, the possibility that our world is just a computer-generated Matrix. There is no way to tell the difference between the Matrix and the real world from the inside.
But if this is, in fact, a computer-generated Matrix, then there must be a computer that is doing the generating. And this computer must exist in the real world.
It therefore follows that the existence of the real world is certain. Either this is the real world, and therefore, the real world exists. Or this is the Matrix--and therefore, as we have seen, the real world exists.
Given that we know the real world exists, the question then becomes: do we have any reason to think that this world is, in fact, the Matrix? No--we have already established that there is no way to tell the difference. For all we know, or can know, this is the real world.
We know just one thing: that the real world exists. And the simplest explanation that fits what we know is that our world is the real one.
Furthermore: G. E. Moore demolished skeptical arguments like these by pointing out that they commit the fallacy of equivocation. They confuse two different senses of verbs like "to be possible."
In English, for example, there is a big difference between "to be possible
for" and "to be possible
that."
For example: it is possible for my computer to be switched off. But it is
not possible
that my computer is switched off. I know this because I am using it to type this message, right now.
From this example, we can see that, just because it is possible
for something to be true, it does not follow that it is possible
that something is true.
It may be possible
for this world to be the Matrix--but it does not follow that it is possible
that this world is, in fact, the Matrix. We would need some additional evidence to establish this possibility--just as I would need some additional evidence to establish the possibility that my computer is switched off.
But as we have
already established, there is no such evidence, and can be no such evidence: from within, the Matrix is indistiguishable from the real world. And in the absence of such evidence, we have no grounds for even supposing that this
might not be the real world.
