Wow, when I posted the question whether a twig or a leaf, I didn't expect the discussion would go THIS far! Well, a friend of mine said apparently the dove brought back a leaf which was on a twig. Don't know if anyone can verify for sure. I'm also wondering that if everything died during the flood, whether the olive could have survived it. If it didn't, whether it could grow back again that fast (150 days more or less, give and take). But of course the days and nights during the biblical era might have been different, I don't know. I'm also wondering that if all of us came from Noah's offspring, then how did we all end up with different colours, built, looks etc? Even allowing for evolution into different subspicies of the human race, it's still hard to fathom.
