Does a junkyard crane give birth to and suckle little baby junkyard cranes who grow up to be adult junkyard cranes who then mate and bear little junkyard cranes of their own? If not, then your analogy is a severe display of ignorance that has absolutely nothing to do with the biological process of evolution.
Machines, such as junkyard cranes, are used by designers and engineers and technicians to make other machines. Often one machine is made -- a prototype. The other machines copy its design. Perfect parallel. That is, if you adult enough to accept it, and not some brat whining.
