Kingpins - if the Ark had 16,000 (presumably 8000 species) creatures on it, what happened to all the other ones who did not make it? There are thousand and thousands of species on this planet including insects, reptiles, mammals and birds (many of the latter can not survive being aloft for weeks and weeks without food).
If you want to use this ancient and dubious myth as proof of whatever, that's up to you. But the facts are against you.
As for animals being on other planets, none so far known in our solar system. On the far planets there may be living creatures but will they be the same as earthly creatures? They may be various species of ameoba.
I am keen to learn something new every day but not from minds fixated on ancient myths.
