A painting requires a painter. A building requires a builder. Creation requires a creator. Order requires an orderer. "On an atheist's worldview" - the theist claims - "how can there be order in the universe? How can a random, unintelligent explosion produce an ordered universe?"
It is not difficult to find online forums and blog posts that proclaim facts and arguments as if they were certain. People of all philosophical alignments will do this. Theists will proclaim what they believe to be indisputable facts like: "Something must have caused the Big Bang", and atheists are often guilty of prophetically declaring their favourite origin story for the universe: "Quantum fluctuations produced the universe" or "Many-worlds explains fine-tuning".
