The concept of Earth's origin from gas and dust particles is often associated with the Nebular Hypothesis, which was formally proposed by Immanuel Kant and Pierre-Simon Laplace in the 18th century.

1. Immanuel Kant (1755):

- In his work, "Universal Natural History and Theory of the Heavens," Kant suggested that the formation of the solar system could be explained through the gradual condensation and rotation of a vast, rotating cloud of gas and dust. He envisioned a "primordial nebula" from which the sun and planets emerged.

2. Pierre-Simon Laplace (1796):

- Laplace further developed Kant's ideas and presented his own version of the Nebular Hypothesis in his book, "Exposition du Système du Monde" (Exposition of the System of the World). He described a rotating, flattened nebular cloud that, as it contracted under gravity, underwent differential rotation and eventually formed rings that condensed into the planets.

These scholars' contributions formed the foundation for the Nebular Hypothesis, which remains a widely accepted theory in modern astronomy. Over time, subsequent observations, scientific advancements, and further research have refined our understanding of the process by which the Earth and the rest of the solar system formed.
