You state this as fact. Link to credible science saying that it is true. This is like saying we have to completely understand how birds fly before we can make planes, or how fish swim before making submarines. Or how muscles cause movement before inventing the wheel. Or how chemical reactions work before we can make fire. You don't have to fully understand the original system or be able to recreate it to make something that exhibits some or all of the desirable properties. This has been shown time and time again.
