Hello everyone,
I’d like to share a thought-provoking idea about a natural phenomenon that may contain clues about drastic atmospheric changes in Earth's past: the rainbow.
In biblical tradition, the rainbow is described as a sign of the covenant between God and humanity, a significant event that occurs after the Great Flood. This raises an intriguing question: why was this phenomenon considered so significant that it was recorded as a historical milestone?
The implication is compelling—could it mean that for many generations, humankind did not see rainbows on Earth? If true, this suggests that something about Earth's atmosphere or sunlight was different, preventing rainbows from forming.
Since a rainbow is the result of light refraction and dispersion through water droplets in the air, two main factors would have to be different in the past for it to be invisible:
1. Sunlight – Was the spectral composition of sunlight different at the time?
2. Earth’s Atmosphere – Were there atmospheric compounds or suspended particles altering light refraction, making rainbows invisible?
The Blue Sun of 1831 and Possible Atmospheric Shifts in the Past
Recently, I came across an article mentioning that in 1831, the Sun was observed as blue. This phenomenon was caused by a massive volcanic eruption in Russia, which released sulfur dioxide into the atmosphere. This gas scattered certain wavelengths of light, reflecting them back into space while allowing predominantly blue and violet light to pass through. Additionally, this atmospheric alteration contributed to a harsh winter.
If this effect was observable during a single isolated event, imagine a scenario where a global phenomenon—such as a series of massive volcanic eruptions or a cosmic impact—maintained an altered atmospheric composition for thousands of years.
This could explain why so many generations did not see rainbows, making their appearance a remarkable and worthy event to record.

An Additional Thought: Pre-Flood Longevity
Another intriguing aspect is the reported longevity of human beings before the Great Flood, as mentioned in biblical accounts and other ancient traditions. If Earth's atmosphere was indeed different at that time, could this be related to human longevity?
Two possibilities arise:
1. Atmospheric Composition – Certain gases or particles may have influenced biological processes, significantly extending human lifespan.
2. Sunlight Spectrum – The light reaching Earth might have had distinct properties, affecting the biology of living beings in ways we no longer observe today.
Of course, this second part is purely speculative, but given how much we still don’t know about Earth’s history and humanity’s past, exploring these ideas could be worthwhile.
I’d love to hear your thoughts on this. Could the rainbow be a natural marker of a significant atmospheric transition? Are there records from other cultures that might support this hypothesis?
