My relationship with Christ isn't based upon what happened long ago, but upon what's happening right now. So I might be convinced to become a TE. But I'm not turning aside from the Lord. Because he's not just the Lord who designed our biosphere long ago, but the Lord who's living and working right now. As Jesus once said, "He is not the God of the dead, but of the living".
That being said, that "chicken-vs-egg" issue regarding DNA repair mechanisms is multiplied by about 200 times, even for simple cells. I'm not expecting a demonstration of the naturalistic assemblage of such a thing in my lifetime.
