In the beginning there was darkness and then for a while there nothing happened. So for years hundreds, thousands, probably even millions or billions or maybe only a minute or two there was absolutely nothing or maybe there was no-one really knows.
So After this long time or not so long time alot happened or maybe not but probably, it was the big bang a huge explosion that triggered the beginning of time, space and life as we know it. This Big Bang was an unbelievably large explosion that sent the galaxies, star systems, and planets flying all over the huge vastness of the universe. The started expanding because of this explosion, as the universe expanded something happened on the planets that had been created.
The planets had some sort of reaction creating life, nothing complicated just single celled organisms. After millions upon millions of years these single celled organisms evolved into more complicated species. The peak of this evolution is humans, us humans are not only the smartest of earthly creatures but are also on the top of the food chain where we will remain as long as those bastard fucking queer bate vegetarians don't get to change things.
