The first stars appeared about 400 million years after the big bang. Galaxies would have formed around 2 billion years later.
Our Sun was formed about 9.2 billion years after the big bang.
The formation of the Earth is the earliest geologic event.
In the first 50,000 years of the universe, the most important event was the rapid expansion known as cosmic inflation, which occurred shortly after the Big Bang. This period facilitated the formation of fundamental particles and the early building blocks of matter, leading to the creation of hydrogen and helium. As the universe cooled, it set the stage for the eventual formation of stars and galaxies, shaping the large-scale structure of the cosmos we observe today.
The event after the first and second events but before the fourth, of course!
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.

In the first 50,000 years of the universe, the most significant event was the formation of the first atoms during a process known as recombination. This occurred about 380,000 years after the Big Bang when the universe cooled enough for protons and electrons to combine and form neutral hydrogen. This led to the decoupling of matter and radiation, allowing photons to travel freely, which is what we now observe as the Cosmic Microwave Background Radiation. This moment laid the foundation for the subsequent formation of stars and galaxies, shaping the structure of the universe.
