Great, then the next time your child is gravely ill I expect you to deny them the medication or medical treatment they desperately need to save their life, because God knows best.
I mean to rely on our brain would be an insult to the God that created us with a brain capable of solving the problems we encounter in life according to your theory.
Heck I suggest just closing your eyes the next time you drive and trust God, oh wait... that would involve you having to use a car... instead of your God given feet... that might be an insult too...
This isn’t medicine we’re talking about. It is design changes in human beings. We have no idea how it all goes together because we aren’t the original designer. It is the epitome of arrogance to imagine that we can even do this.
You can keep your arrogance. I’m not about to start thinking I can out create God. As for those who imagine science can reverse engineer humans, remember the punchline to that old joke. The one where the scientist says he can create man out of nothing just like God. In the joke, God says to him, “Create your own dirt” [out of nothing, first].
