However, you are right that this provides "a great leap in human understanding of the universe". As Gheld has stated, this not only adds new data to the Big Bang Theory, but pushes forward our understanding of General Relativity, Quantum Mechanics and most importantly, Quantum Relativity.
It's nearly impossible to overstate how significant this discovery is.
As for the "theory", "fact" and "law", theories contain facts and laws. The Universal Law of Gravitation is part of Newton's theory of Gravity. The Laws of Thermodynamics are a part of the theory of thermodynamics.
Laws describe phenomena and theories explain both phenomena and laws. Einstein's theory of gravity (General Relativity) explains Einstein's Law of gravity. It even explains Newton's Law of gravity under conditions of low energy. The theory of evolution explains the fact of evolution.
Creationism isn't even in the same ball park. It doesn't even rise to the level of unproven hypothesis. If you want to classify it, it's under "fairy tales".
