In the beginning god created the empty set but we didn't know if it was unique or not so god said to compare sets you compare what they contain and we knew the empty set was unique. We were happy because we had a set but all was not well because we still didn't have numbers or any other sets but the empty set, then god said let us be able to create subsets by a property and we were confused because our only set had no elements, so god gave us a way to create new sets we could now pair together sets to create new sets and it was good because we now had sets we could take subsets of and we were happier but we were limited to sets that had size 2 so god said I will allow you to union sets together and it was good because we could now have sets of any size we wanted but there were still subsets we couldn't take because we had to have a property and not all subsets have a property to define them so god gave us the power set and it was good because we could now have any subset we wanted (kinda)...
