There is no evidence to support the claim that the true history of planet Earth is being actively suppressed. The field of Earth sciences, including disciplines such as geology, paleontology, and archaeology, is continuously evolving as new discoveries and advancements are made.
Scientific knowledge is built through rigorous investigation, peer-reviewed research, and consensus among experts in the respective fields. While our understanding of Earth's history has certainly evolved over time, it is not the result of a deliberate suppression of information but rather the natural progression of scientific inquiry.
It is important to approach any claims suggesting a conspiracy to suppress knowledge with a critical mindset. Extraordinary claims require extraordinary evidence, and without substantial proof, it is not reasonable to assume that a vast conspiracy exists to suppress the true history of our planet.
