Honestly though, in my opinion, this is a terrible answer. The clear implication of his question is "we don't know yet... therefore God." If that is his reasoning, then he is a thoroughly uncurious person, which is the exact opposite of what a good President is.

So any POTUS who believes in God is unqualified? Because if you have a conversation with an atheist about the original creation, you're often accused of using "The God of the Gaps" for anything, even if you put forth an articulate reason why you believe a higher power is the simplest and most logical explanation for that phenomenon ... Screaming "God of the Gaps" is becoming almost as you-can't-prove-me-wrong-so-I'm-right as shouting "God did it!"
Who's to say someday we won't find a "gap" that actually can only be explained by the works of a being outside of space-time? Endlessly posturing that there will always be a non-designer related answer to the ultimate question isn't exactly logical, either.
