Don't ever be lazy enough, defeatist enough, cowardly enough to say "I don't understand it so it must be a miracle - it must be supernatural - God did it”. Say instead, that it's a puzzle, it's strange, it's a challenge that we should rise to. Whether we rise to the challenge by questioning the truth of the observation, or by expanding our science in new and exciting directions - the proper and brave response to any such challenge is to tackle it head-on. And until we've found a proper answer to the mystery, it's perfectly ok simply to say "this is something we don't yet understand - but we're working on it.”.
