Highdose, why do you complicate such a simple issue.... let me explain...
1) All contnets were connected before flood
2) Jehovah miraculously directed all the animals to go to the Ark
3) During the flood continets were torn apart, but remained connected by "bridges"
4) After all the specific animals used the bridges to get on their islands, these bridges miraculously crushed into the sea (so today there is no evidence of them... BTW why shoud we need some???)
I have not made anything up, everything is based on research of WT scientist and published in WTBS publications. (You can find everything here on JWN)
So where do you see any problem darling?
(Oh you all time doubting apostates...)
From Albert with love
