Do we believe in fairytales that are not scientific?

I read a question before about myths and it basically asked about fairytales or something along the lines of that but the answers werent good enough. Normally, when talking to non-Muslims but mainly atheists they usually make jokes out of things like the prophets split the sea and I know this isnt from the Quran but the example of turning wine into water. Things like that. They say we believe in fairytales that arent true. If I think about it fairly and from both sides it does seem understandable that many atheists would think like this. In the question I read it said something like Muslims have records for the actions but that only shows the Muslim side and not other sides. The question is about greeks but I am talking about stories in general. Why is believing in these things seen as so ridiculous? Why do we believe in these things when they defy physics and things like that? Saying that God can do whatever doesnt really make it true or set the argument because then in that case all the Gods of the other religions could have power to do the actions and they could change science so the miracle could happen. Also in the question it says that evidence of miracles like this havent come up recently and that is kind of true. We havent seen things like moons splitting etc and now that science is developing we understand the effects it will have on the Earth too. Is the belief in these stories/fairytales ridiculous and not scientific/logical?
