I respect your view on that, but i happen to disagree for a number of reasons. The least of which is the fact that historically it is recorded that splitting of the moon was a physical miracle because even the travelers who were bound towards Makkah, when questioned upon their arrival if they had witnessed anything unusual confirmed that yes they had seen the moon split and then re-attach. This proved false the allegations the pagans were levelling against the Prophet (pbuh) that he had cast witchcraft spell over them. But some among them who were wise responded by saying that witchcraft spell would only effect the attendees and not those who are not present, hence them approaching the travellers.
Also you may find the following helpful to my view on this (not a convincing source, but something to the effect):
PS: Sorry for going off-topic, PCG. However i feel the validity of one miracle as being physical reflects the realness of other miracles as being physical as well. At the end of it all, it boils down to faith and belief. And everyone has their own view.
