Struggling with beliefs in miracles

In the quran there are miracles like turning a stick into a snake, splitting a sea, reviving dead people or whatever else you can think of. I'm really struggling to believe in this and need to understand something about them. These miracles if claimed by anyone know they would be deemed a madman, I also tried and I can not find a single piece of evidence to back them up. To me it just seems like another myth or metaphorical story not true. Its also just weird to me how miracles go on throughout history and as soon as human civilisation builds technology to convey messages and record things with ease and effectively the miracles completely stop. Some people may say that you have to trust Allah and your knowledge is limited or this is a test. Believing in something with little to no evidence just generally seems wrong to me and you can say life is a test but that cant be the answer to everything you have. An answer like that is probably the reason why a lot of ex-Muslims left Islam as they may have questioned themselves only to receive such an answer. Are the stories in Quran tales, metaphors or do we actually take them literally and what evidence is there to back them up?
