I'm having a debate with a friend and I'm saying that at some point down the chain of creation, something must have always existed otherwise nothing would exist.
a exists because b created it.
b exists because c created it.
c exists because d created it.
but there is a problem with this, if the list goes to infinity, then A would never exist. At some point down the line there needs to be something which has always existed. Whether it's god, energy or a 3 headed dragon riding a pony. Something must have always have existed otherwise A wouldn't have ever been created in the first place.
