Well, this confirms again that you have a problem only in UDA-step 8.
Here you are just begging the question by defining existence by
Let me ask you two questions. First I define a big-robust physical

+robust-universe entails the complete reduction of physics to computer
science. If you say no, can you pinpoint the step in UDA1-6 you
disagree with. If you say yes, then we might have to come back on MGA.
