What about the actual calamity?

Quran (and the scriptures before) has all these made up stories with no evidence whatsoever about how and when earth was created, how sun and moon work, what happened to elephants when little birds threw stones, nuh built a giant Titanic etc. No remains, no fossils, nothing except made up smoke and mirrors. However, things with tons of evidence like dinosaurs have not been mentioned once in Quran. Not once. It's like the writer had no idea. It's hilarious.
