Star Trails Destroy the Globe and show with no doubt that earth spin does not cause the star trails we see. A video on The Sun And Moon Family United channel (https://youtu.be/h6H757a_WHo) shows brilliant work by Dave Marsh with lunar and stellar trails. There are many gems in that video and I HIGHLY suggest watching it. More will come from that particulart video on this channel. The earth is FLAT! No evidence shows either curve or spin.
