I'll never be set in stone either way until Jesus tells me himself.

I look and I see... deer for instance.... how many various types of deer... of fish.. of birds... etc..

I look at the human race and I see the same thing. Upon the Ark was Noah, his family his sons their wives, who could have literally carried the genes of several races of people between them, the sons wives.

But there may be more.

I later read in the bible that there were still giants after the flood... David killed Goliath remember? So somehow, even some of them survived that. I know it was God's intention to save Noah, and that he did... but there's no rule that says polar bears didn't survive floating on icebergs just like a few siberian guys or that not a single other boat existed in the world and saved some others too. I'd say that's actually highly unlikely, that no other boats existed. Noah's job was to save himself and his family, this ine of Adam, the animals, that he did.

But I also know God and if he sent a flood to wipe out a lot of people or horror or misery or plague whatever... and if a certain guy that he wasn't crazy about gets the gumption to jump in his boat and ride it out... I'd say it's highly unlikely God would look down and overturn the boat. Likewise... the bible is the record of Adam... of that geneology, it tells us that. But later it we also learn that Nebechednezzar knew God, didn't obey him, but knew him.

I knid of do lean toward other cultures existing though we may not know their stories like we know the bible. It is interesting how people in the middle of nowhere will claim to know Jesus, even before missionaries arrived. There are stories like that.

The bible is the record of Adam. But others not written of in there have also known God. Noah found grace, favor, in the sight of God is all the book says. There may have been others, in some remote corner of the world, hard to say really.
