If you can start asking questions like “do we actually need a baby”, “what are the specifications for hair color and nose length”, “does it need to be a human baby”, “how about we start at an embryo instead” etc. the whole equation changes. But most people asking for the estimate aren’t actually interested in providing any of that information.
They want to give you a vaguely defined blob of half finished specifications, and expect a perfectly accurate assessment of the time it will take, and also to be able to change the vaguely defined blob as they go along without effect on the given estimate.
