You have the big bang, where space and energy explode into a plasma in femtoseconds, and then the whole thing cooled and expanded into a cloud of matter fairly quickly
Since then, it’s been slow. It’s atoms attracting each other through gravity for millions of years
Space is so big, humans can’t begin to understand it. A billion years are so long, humans can’t begin to understand it
It’s all happening insanely slowly, really
