Here's the trick, Big Bang Theory and Evolution stem from the same mindset: "There is no God".
That's why they get talked about in the same breath. I agree facts are facts, and here's a fact: We have no reliable records from more than 10-12 millennia ago, and those are sketchy at best. We can have absolutely no idea, no matter how good the math is, how the Universe began without actually developing a Time Machine and going back to see for ourselves. The same is true of Evolution Theory, we can't know how we got here unless we travel far enough back to find out how or why.
All these arguments do is serve to divide us as a species. I'm one day, one way or another, the argument will be settled. However, there are aspects of life that science is all it's complexity can't explain and isn't equipped to explain, because according to science it can't or shouldn't be that way. This is where religion comes in. It's no mistake that religion has slowly moved back from primacy in our daily lives, as science has explained different aspects of life and the universe, religion didn't have to anymore. But, for every answer, a new question and every question a new aspect of religion has risen. People need to have things explained in life, when science can't do it, they turn to religion.
I belive, and this is my personal belief, there is an almighty, all knowing, personal God that created the universe at sometime in the past. He set the rules and conditions into place that the Universe operates on. He loves his creations in a way that no mortal being can comprehend, and as such has set paths before us to lead us to where we will be at both our happiest and greatest. He has given us the ability to understand most of creation, but it is so vast that we will never be able to comprehend it all.
