One must develop a testable theory of a transforming agent.
That would be good if it were possible. Darwin spent most of his life looking for supporting evidence for his 'transforming agent' - natural selention.
Likewise I have spent 24 years, and written 5 books, outlining what I believe is supporting evidence for the God Gametes theory.
Yet the GG theory, like Darwinism, cannot be proven. To prove - test - one would need to wind the clock back 13.7 bill years to the big bang - then of course someone is going to ask; 'how did the big bang happen?'
