We all know days are longer during winter and shorter during summer. Ive seen people on both sides of the argument use the fact that the length of day changes as evidence for their argument. Im pretty new to this whole idea of a flat earth, but to me the fact that length of day changes seems more like evidence that earth is flat rather than round. If it were round wouldnt there be 12 hour days and 12 hour nights everyday? I would love to hear other opinions on this, from both sides of the argument. Thanks.
