Pegasus and Burraq

I have read "qasasul Ambia" like when i was 8 years old. they were good stories for a kid. but now i wonder what is the evidence of all that happening? does it come from any authentic source? i dont think so.
mojza is simply something that makes your aql go "wow" or something like that. something that makes your reason "Aajiz". that might have an explanation but maybe not at the time that it happens. so I dont think some miracle might be explained. the rest are stories created by the adherents.
