I am afraid I disagree. Evidence leads to the formulation of conclusions. Facts are not the same thing at all.
In order to reach any conclusion, you have to formulate a hypothesis, and then try to disprove it. If after ten years you have failed to disprove it, and colleagues around the world have also failed to disprove it, you may conclude that you have discerned a 'fact'. Actually, you haven't. All you have discerned is a hypothesis which has not yet been disproven, and which may or may not be correct.
At that point most scientists will probably assume that it is correct, and work accordingly, but this still does not equate to having a fact.
My faith is not based on the inerrancy of the Bible, but on the inerrancy of God. Different thing entirely.
How can I answer that?
I am sorry but that is just twaddle. Atheism is a statement of belief in relation to God. Nobody is born able to articulate, or even conceive, the thought that God does not exist. Babies are born in a state of not knowing, but they are most certainly not born as atheists. That is just plain silly.
For someone who claims affinity to science, you rely on anecdote a lot.
I don't. I leave science to do what it does, and I leave faith to do what it does. The two are not incompatible in any way.
Faith is not just about believing without evidence. Do you honestly think so little of theists that you think we can believe something for thirty or fourty or fifty or more years with no evidence whatever? That is just bizarre.
Not a great deal, to be honest. I vote for the people I think best for the job; their faith has nothing to do with that.
Time, as any scientist will happily tell you, began at the Big Bang. Therefore there is nothing that science can say about 'before', because you cannot have before outside time. Try asking a scientist what happened an hour or ten hours or a year before the Big Bang and he will have nothing to say;the question is meaningless.
God is outside time, aka eternal. He created time alongside everything else, but he is not answerable to it or subordinate to it. How did he come into existence? He didn't; he is eternal. Coming into existence necessarily denotes a time before, then a time of beginning, and a time of continuation, all of which are applicable to those of us in creation, but not applicable to the Eternal, who is not in creation. There is no time before God, because God created time.
