I am now convinced that the octagonal shape is due to the aperture of the diaphragm, but this still does not explain the lights.
There is necessarily an explanation for the observed phenomenon. This explanation may be of natural origin or, more exceptionally, related to a phenomenon that is not yet understood.
Science prioritizes natural hypotheses, not by rejecting the supernatural, but because they are testable, reproducible, and falsifiable. This does not mean that other forms of explanation are impossible, only that they cannot be validated without measurable evidence.
The human mind is indeed structured to seek rational causes, as this framework allows for the construction of coherent and predictive models of reality. However, absence of evidence is not evidence of absence.
The hypothesis of life in another universe, endowed with an intelligence superior to ours, cannot be dismissed a priori. As long as no experimental data allows a definitive conclusion, this hypothesis remains speculative but logically acceptable, just like any other unproven explanation.
