Quite a few scientists are changing their minds about evolution, simply because there are, indeed, myriads of "complex organs"..."which could not possibly have been formed by numerous successive, slight modifications," which have convinced such notable former-evolutionists such as William Dembski, Scott Minnich, and Dean Kenyon that the probabilities are simply too infinitesimally small to be considered scientifically possible. There are MANY more!
Just look for the amazing results of studying the little "out-board motor" of the paramecia flagellum. You have an amazing mind, if you believe that chance and circumstance could bring this about, without any creator or designer. But each must place his faith in something or Someone, and you are as free as anyone to make up your own mind.
Look for the video, "Unlocking the Mysteries of Life", and take a nice, long drink of real research in detail.
I propose: it takes greater faith to believe that Chance and Spontaneous Creation could design this awesome universe, than it requires to believe that an Eternal, All-powerful Creator did it, with the simple power of His Word.
