if the Earth is 4.5 billion years old, and the oceans started filling up about 3.8 billion years ago, then it took about 700K years for water to start forming.

So I guess the question is, how long did it take for Venus to become too hot for oceans?

Well, my understanding is it happened about 4 billion years ago.

but 4 billion years ago there was still no water on the Earth...so maybe, it's the case that Venus transitioned before water could have formed in the first place?
