You think you have a pretty good idea of how it all came about, the Universe that is, but do you really? Probably not, but neither does anyone else, so it's OK.
The best we can do is speculate, but if history has taught us anything is that we usually get it very, very wrong in the long run.
Still, if you need a quick refresher on what's happened in the past 13.75 billion years or so since this Universe came into existence, you can check out the video above.
It goes from the Big Bang, the first galaxies, our solar system being created to life showing up on Earth, the dinosaurs getting wiped out and all the way to man setting foot on the Moon.
Quick is the key word here, the entire thing lasts 90 seconds, but no major plot turn is left out.
