Alkaline earth metals do not occur freely in nature because they are highly reactive and readily form compounds with other elements. This reactivity makes it difficult for them to exist in their pure metallic form in the Earth's crust. Instead, they are commonly found in various mineral compounds, such as carbonates, sulfates, and silicates. These compounds are more stable and allow the alkaline earth metals to exist in a more chemically balanced state. **

Press did not report on the near catastrophe when a comet flew extremely close to Earth back then because the event likely occurred before the era of modern mass media and widespread communication. Additionally, the technology to detect and track such celestial events may not have been as advanced as it is today, making it easier for a close encounter to go unnoticed. Lastly, the event may have been downplayed or kept secret by authorities to prevent panic or fear among the public. **

The lack of press coverage on the near catastrophe when a comet passed extremely close to Earth could be attributed to several reasons.

Additionally, the scientific understanding of comets and their potential impact on Earth may have been limited at that time, leading to a lack of awareness and urgency in reporting the event. Lastly, governments or authorities may have chosen to suppress information about the near catastrophe to prevent panic or maintain control over the situation. **
