Thank you, R.Hassan, for your reply. I appreciate it.
The essence of the article is to point at ourselves, our human brains. We are doing something with our brains that we subsequently fail to recognize.
The universe is the highest level, and it is non-functional.
If we add another larger layer to it, such as with multiverse, by itself a good proposal, then all we did was kick the can down the road because the multiverse has then become the non-functional largest layer.
So, nothing was changed by doing that. We still have the largest level being non-functional.

The real trick the brain plays on us is not that the universe is real. It is the fact that it is non-functional that is the surprise.
The conclusion is (and must be) that the Big Bang was a one-time event. It was a negative event in that it undermined the prior reality (whatever that was). Therefore, the largest layer of reality is one where the function disappeared.
Mathematician Gödel showed this already some 100 years ago. He called it his Incompleteness Theorems, and the result of his proof was that the completed levels are not found at the largest level but one level below the largest level.
I always use silly analogies, but basically if we have as truth that people can grow mustaches, then we cannot take that truth to be true for all people. Another truth that people can keep their high voices throughout live is also not applicable to all.
It turns out that all truths cannot be brought to the highest level. They find their maximum area one level below the highest level. People with mustaches will never be all people; people with high voices will never be all people.
Another way to see the point is by understanding that there never was nor ever will be a human being who is male, female, old, and young at the same time. An archaeologist trying to find the single human who is the ancestor of all is not very smart because that ancestor will have been male or female and not both. The top level will not contain the complete set as a single truth, and will therefore be an incompleteness.
In conclusion, the largest level is the context we understand without any problem. Yet it is not the contents, exactly as you also proposed with our universe existing in a larger context. To show you how it does not help to add another layer, I am proposing that the multiverse itself exists inside an even larger reality call the God Domain in which there are many multiverses. I hope you see that I am being silly. I did nothing but top the non-functional top level with another imagined non-functional top level, a meaningless exercise. The brain is having fun, but did not produce anything useful.
Thank you for your reply. I really do appreciate your response.
