Your premise partially relies on the idea of ancient whales existing. But the sediments we find whales in are all relatively young so it weakens your argument.
Your argument also partially relies on knowing better than God how to design things. You are clearly not qualified to claim this thus your argument is further weakened.
Your argument also partially relies on the idea that mutation plus natural selection can turn a land mammal into a whale and then what you call an ancient whale into all the differing whales we see see today. Science says mutation+NS does not have the power do do this.
Thus, your narrative is busted, you don't even have a theory.
