An Unsolved Mystery Experience

(Posted today 30th sept 2020) I'm not quick to be fanciful as I tend to explain every mystery in a natural, rational, scientific way. Yet one of the few unexplained mysteries in my life which refuse to be erased from memory was when there was an earthquake years ago And both dad and I felt the presence of heavy ginormous wingspans beating on our roof as if that huge flying creature was causing the quaking and shaking of the earth beneath us. Lots of thoughts still roll in my mind to explain it. Was it a supernatural Angel causing the jolting or was it some flying dinosaur like a pterosaur which hadn't gone extinct but was too evasive and elusive? to be documented by discoverers. I could try inking a dactyl on pterodactyls but I just can't think of a rational explanation of what we heard and felt but never saw . Seeing is believing but so is hearing and feeling. Its wings and flapping wing beat had felt and sounded like some mammoth bird bigger than an ostrich . So what in the big wide world was this creature right on our roof overhead that we never got to see?
