The Big Bang was an explosion like none other since. So it cannot be compared against other explosions that have happened since then either. The Big Bang did something that no other explosion has. It created reality as we now know it. Although not immediately. It took hundreds of millions of years for things to cool down enough for matter, time and space to even exist. Before that it was just an expanding ball of energy. That's what's so strange about the event. It was a singular occurrence in our reckoning. What it did is nothing short of completely astonishing too. Every mote of dust in this whole Universe owes its very existence to that one moment. We are the echo. An aftershock? I am not boffin enough to know.
