If you have no other information or choose to ignore anything you can't detect with your five senses, you have no knowledge outside your own personal experiences, you are illiterate, you lack curiosity or the ability to reason or act beyond immediate sensory input, then a flat earth is perfectly intuitive. Thousands of species have been highly successful in survival without the concept of a round earth. Although scientific evidence overwhelmingly proves the earth is not flat, such awareness is not essential for survival 😉
