Everything must conform to the assumption that only natural processes could be responsible-and even if the evidence shows that it's not possible, you stick with the original program.
Of course this assumption is used and for very good reasons.
1) It has worked over and over and over again. You want to play a god-of-the-gaps game; there is something unknown so god must have done it. However, this game has proved to be a mistake throughout history. Why should we think that, finally, this time it is actually correct?
2) If we assume instead that a miracle occurred then study is over. Such an event is not something that can have scientific study applied since it can have occurred in any way at all and leave or not leave any evidence at all.
And there is no evidence showing it is not possible. It is hard to find evidence that it is possible. It is harder to find evidence of exactly how it happened and it is really, really hard to prove that there is no way at all it could have happened.
If we go with your wishes and allow for none natural processes then just how would we learn anything at all? <----- thread:
