Having an antenna design is only a small part of the equation.
Ah, but it is the central, key, most impotant part of "the equation" that blows apart your entire belief system in design
Irrespective of the computer involved, the materials used to construct the system, the engineers who constructed the systems, the intelligence involved in determining what the designs were useful for, the fact that the antennas did not construct themselves...
... nowhere in all of this is found the information that carries the design of the antenna.
Where is the source of this information???
It is exactly the same source as the entirety of evolution. It is the environment.
If you wish to preserve your belief in the necessaity of a designer, you would do well to run away at this point and try to forget the above, as it is the death blow to Intelligent Design.
