Another rational explanation.
You are familiar with this image;
Try this with deeper reflective thinking.
I presumed you are agree,
1. scientifically [
human-based scientific FSK] the Universe began with the Big Bang with a bust of particles expanding in all direction; like the above image with no specific pattern of things.
2. Then the particles got together to form denser clusters or bundles of particles.
3. The process has been going for 13.7 billions years with denser and denser clusters or bundles of particles up the present.
4. Around 3.5 billions years ago, the first one-celled animals emerged. Do you think they perceived these dense clusters as stars in a sky. No, No, No..
5. Later after a few billion years, we have animal with pattern recognition abilities who would perceive these patterns as things within the specific cognitive FSK.
6. It is only at this stage that there is emergence and realization of particular things of reality [separating the discrete from the continuous] specific to these animals. There is no abilities for these animals to know and describe them.
7.The above continue till existence of humans with emergences and realization of reality specific to the FSR which is then perceive, known and described with the specific FSK.
8. But note these emergences and realization of the discrete is grounded on the ever present continuous soup of particles.
9. But this 'soup of particles' is the resultant of
1 above which is conditioned to the human based science-physic FSK.
10. Yes, it's circular and the point is there are no mind-independent reality, it is always entangled with the human conditions.
11. You may bring in ex nihilo nihil fit or principle of sufficient reason, all these are all human [subject] made.
What we have are only first-person experiences, thus subjective.
To make it less subjective, we have to rely on a collective-of-subjects' experiences via a human-based FSK to find shared views based on verified and justified empirical evidences, so that they are objective [independent of a subject's views].
From the above, there is no way, one's speculation of an absolute human independent reality can exist at all. That speculation is an illusion and to insist is delusional.
Yours is a psychological issue that need philosophical therapy.
