Ok, lets assume that God created everything as is, with no evolution involved. This is what JW's teach based on a singular vague verse in Genesis. Made according to their types
THEN, the flood! Anything that is alive today would have to have been purposely saved by being in the Ark.
Noah didn't collect the animals, remember they came to him by the divine Will. Animals came to him
So all animals are alive today due to the choice of God, twice over.
Satan didn't corrupt any animals, there is ZERO scriptural proof of this. Surely this would warrant a single mention somewhere if it happened?
Satan didn't create any new animals, God alone is Creator.
