Can you tell me where you find that definition for evolution? Because in this post I linked and posted the definition of evolution from:
1. The dictionary
2. Wikipedia (a compendium of information, and it's typically left-leaning)
3. Talk Origins (a pro-evolution website)
And they all pretty much agree. And the concept of the Big Bang doesn't factor into ANY of those definitions.
So can you please show where you're getting that definition, because they need to be corrected.

Fixed that for you...
I know the reason you don’t want to admit that the evolution of life is part of evolutionary theory is because you can’t defend the origination of life from non-living matter. However, that’s what IS part of evolutionary dogma. Nonetheless, if you’re so smart, tell me: How did life come about? Did it evolve out of non-living molecules, or was it created by God?
