Nobody really know if aliens truly exist, I only watched on the movies about aliens and how they even look like and I don't also know how true their identity is, painting them to have big ears, massive statuses, long nails accompanied with a mysterious kind of voice, I don't know how true are these characteristics of aliens but have you've mentioned in your writing that research is constantly on going without a prove, well time would tell, if actually these creatures exist. I wish you best of luck
