Following scientific principles can never lead a man to become an Atheist. BTW, a man has to BECOME an Atheist just as he becomes a Christian, Muslim, Hindu, or any other religion.
A man adopts a religion in response to a prompting from within himself.
He becomes an Atheist by denying that prompting, probably because he interprets it as a threat to his Self, which it is.
Any Scientist worthy of the name knows there are things which can only be experienced and are not suitable for scientific investigation. Such as Love, for instance. It is real and it's effects are observable, but it can't be quantified or analyzed.
So, demanding "evidence" for the existence of a Higher Power is a cop out.
You might as well demand dehydrated water when you are thirsty.
