Starting of World.🌍

 


The question "World start" is quite broad, but if you're referring to the origins of the world or the Earth, here’s a general overview:


1. **Big Bang**:

   - Occurred about 13.8 billion years ago, marking the beginning of the universe. It led to the formation of matter and the eventual creation of galaxies, stars, and planets.


2. **Formation of the Solar System**:

   - About 4.6 billion years ago, a molecular cloud of gas and dust collapsed under its own gravity, forming the Sun at its center. The remaining material formed a protoplanetary disk, from which the planets, including Earth, formed.


3. **Formation of the Earth**:

   - The Earth formed about 4.5 billion years ago from the accretion of dust and gas in the protoplanetary disk. Over time, it cooled and differentiated into the core, mantle, and crust.

   - The early Earth experienced heavy bombardment by asteroids and comets, which contributed to the formation of its oceans and atmosphere.


###(Early Conditions and Life)


4. **Hadean Eon**:

   - The first 500 million years of Earth's history. The surface was extremely hot, and the planet was frequently bombarded by meteorites.


5. **Archean Eon**:

   - Started around 4 billion years ago. The Earth’s crust cooled enough to form continents and early oceans.

   - Life began to emerge, with the earliest known microorganisms appearing around 3.5 to 3.8 billion years ago.


6. **Proterozoic Eon**:

   - Spanned from 2.5 billion to 541 million years ago. Marked by the buildup of atmospheric oxygen (the Great Oxidation Event) and the appearance of more complex life forms, including multicellular organisms.


7. **Phanerozoic Eon**:

   - Began 541 million years ago and continues to the present. It is divided into three eras:

     - **Paleozoic Era**: Explosion of diverse life forms in the Cambrian period, the formation of extensive forests, and the assembly of the supercontinent Pangaea.

     - **Mesozoic Era**: Age of reptiles, including dinosaurs, and the breakup of Pangaea.

     - **Cenozoic Era**: Age of mammals and the rise of humans.


### Human Evolution


8. **Hominins**:

   - Human ancestors diverged from the common ancestor with chimpanzees around 6-7 million years ago.

   - The genus *Homo* appeared about 2.5 million years ago, with modern humans (*Homo sapiens*) emerging around 300,000 years ago.


### Modern Civilization


9. **Development of Civilizations**:

   - The advent of agriculture around 10,000 years ago led to the rise of settled communities and the development of complex societies.

   - Human civilization progressed through various stages, including the Bronze Age, Iron Age, and various historical periods marked by the rise and fall of empires, technological advancements, and cultural developments.


This timeline provides a broad overview of the Earth's formation and the development of life and human civilization. If you were referring to a different aspect of "world start," please provide more context, and I'd be happy to elaborate.
