Why not?
Because ID and SETI are exactly the mathematics. However, for SETI, organization in a much simplier “radio wave” is an AUTOMATIC indication of design; yet there is NO acceptable level of organization (complexity) within any living body for which the evolutionist would be willing to apply Probability Theory.
In other words, Probability Theory will NEVER be allowed to be applied to any component of a living organism, no matter how complex the design, because they all know that life DESIGNED itself through evolution. Therefore, how could any of these scientists make the argument that probability theory is to be applied to radio waves (in ordered signals), but can NEVER to life itself.
In other words, if you believe life designed itself, why couldn’t an radio wave also have designed itself or have become ordered when it passed through such-and-such or because of mother nature or whatever?
