>>13622285Well, it just appeared if you don't believe in the (imho very logical) progression presented by the Big Bang theory.
Now, what was before the Big Bang, where that whatever it was come from, and why it expanded into a complex universe, that is still a mistery, and we might as well call it divine intervention.
Regardless, nothing changes that the interstellar medium that eventually condenses into solar system is very hydrogen rich, with traces of heavier elements. So you have a mass of cooling hydrogen condensing into a planet, some oxygen, enough of an atmosphere for it all to not evaporate, and voila.

However, the necessary cooling down took less than a millionth of a second, so it wasn't instant, but pretty fucking quick.
