You can't prove a negative
Proof by contradiction.
Fatima? Miracle? Lol.
From the same article:
"Steuart Campbell, writing for the 1989 edition of Journal of Meteorology, postulated that a cloud of stratospheric dust changed the appearance of the sun on 13 October, making it easy to look at, and causing it to appear yellow, blue, and violet and to spin. In support of his hypothesis, Mr. Campbell reports that a blue and reddened sun was reported in China as documented in 1983.[28]"
Joe Nickell, a skeptic and investigator of paranormal phenomena, claims that the position of the phenomenon, as described by the various witnesses, is at the wrong azimuth and elevation to have been the sun.[29] He suggests the cause may have been a sundog. Sometimes referred to as a parhelion or "mock sun", a sundog is a relatively common atmospheric optical phenomenon associated with the reflection/refraction of sunlight by the numerous small ice crystals that make up cirrus or cirrostratus clouds. A sundog is, however, a stationary phenomenon, and would not explain the reported appearance of the "dancing sun". Nickell suggests an explanation for this and other similar phenomena may lie in temporary retinal distortion, caused by staring at the intense light and/or by the effect of darting the eyes to and fro so as to avoid completely fixed gazing (thus combining image, afterimage and movement). Nickell concludes that there was
"..likely a combination of factors, including optical and meteorological phenomena (the sun being seen through thin clouds, causing it to appear as a silver disc; an alteration in the density of the passing clouds, so that the sun would alternatively brighten and dim, thus appearing to advance and recede; dust or moisture droplets in the atmosphere, imparting a variety of colors to sunlight; and/or other phenomena)."
Paul Simons, in an article entitled "Weather Secrets of Miracle at Fátima", states that he believes it possible that some of the optical effects at Fatima may have been caused by a cloud of dust from the Sahara.[30]
From the same article: "De Marchi claims that the prediction of an unspecified "miracle", the
abrupt beginning and end of the alleged miracle of the sun, the
varied religious backgrounds of the observers, the
sheer numbers of people present, and the
lack of any known scientific causative factor make a
mass hallucination unlikely. That the activity of the sun was reported as visible by those up to 18 kilometres (11 mi) away, also
precludes the theory of a collective hallucination or
mass hysteria, according to De Marchi.

A statement was issued later by witness Professor Almeida Garrett:
"The sky, which had been overcast all day, suddenly cleared; the rain stopped and it looked as if the sun were about to fill with light the countryside that the wintery morning had made so gloomy. I was looking at the spot of the apparitions in a serene, if cold, expectation of something happening and with diminishing curiosity because a long time had passed without anything to excite my attention. The sun, a few moments before, had broken through the thick layer of clouds which hid it and now shone clearly and intensely.
"Suddenly I heard the uproar of thousands of voices, and I saw the whole multitude spread out in that vast space at my feet...turn their backs to that spot where, until then, all their expectations had been focused, and look at the sun on the other side. I turned around, too, toward the point commanding their gaze and I could see the sun, like a very clear disc, with its sharp edge, which gleamed without hurting the sight. It could not be confused with the sun seen through a fog (there was no fog at that moment), for it was neither veiled nor dim. At Fatima, it kept its light and heat, and stood out clearly in the sky, with a sharp edge, like a large gaming table. The most astonishing thing was to be able to stare at the solar disc for a long time, brilliant with light and heat, without hurting the eyes or damaging the retina. [During this time], the sun's disc did not remain immobile, it had a giddy motion, [but] not like the twinkling of a star in all its brilliance for it spun round upon itself in a mad whirl.
"During the solar phenomenon, which I have just described, there were also changes of color in the atmosphere. Looking at the sun, I noticed that everything was becoming darkened. I looked first at the nearest objects and then extended my glance further afield as far as the horizon. I saw everything had assumed an amethyst color. Objects around me, the sky and the atmosphere, were of the same color. Everything both near and far had changed, taking on the color of old yellow damask. People looked as if they were suffering from jaundice and I recall a sensation of amusement at seeing them look so ugly and unattractive. My own hand was the same color."
"Then, suddenly, one heard a clamor, a cry of anguish breaking from all the people. The sun, whirling wildly, seemed all at once to loosen itself from the firmament and, blood red, advance threateningly upon the earth as if to crush us with its huge and fiery weight. The sensation during those moments was truly terrible."
Why in the hell would you use "philosophy" to explain the existence of anything in the physical world?
Because it's a lot better at providing reasons than science is.
