The splitting of the moon: any metaphoric explanation?

Verse 1 of Surah Al-Qamar very clearly references the story of the moon being split. Mostly I hear the explanation that includes our prophet (PBUH) and the Quraish witnesses. However, I am also convinced that a splitting of the moon is scientifically impossible. Is it possible that this verse has a deeper meaning? Is it perhaps written to illustrate that even a miracle of such scale would not convince a person who is a disbeliever at heart? Or perhaps the word splitting would not necessarily mean a very large part of the moon was split from it, or that both parts of the moon weren't joined back together after the miracle? I ask this question because I am a recent convert, but was raised as a sceptical atheist who still has a strong desire to see logic and faith joined together!
