There are around 6 million species of land animals. The only arc they could possibly have made is one which would handle the animals for a local flood. Even a modern ship of steel wouldn’t be enough for what you suggest.
Because the promise was about God not sending a flood to save humanity by destroying human civilization mired in corruption so it could start again, not about never allowing any natural floods let alone about destroying all life throughout the universe. God didn’t think we were worth the price as it was, let alone the price of doing so when human civilization had spread over the whole globe.
