#Cloud of Dust

The cloud of dust refers to the aggregation of fine particles (such as volcanic ash and rock fragments) that is believed to have covered the entire Earth during ancient times, generated by large-scale volcanic activity and frequent meteorite impacts. This cloud played a role in blocking harmful ultraviolet rays from reaching the surface and simultaneously created an environment where specific chemical substances could condense and concentrate within the cloud or its lower layers, potentially promoting chemical reactions crucial for the origin of life.
