What piece of evidence convinces you the most that UFOs are aliens/NHI?

Could be a person that you believe the most. Or a video etc. I’m losing hope and would love someone to point me in the direction of some interesting things to consider. Could be your own personal experience. And if you don’t want to post on here for fear of ridicule I would love it if you had time to DM me.

Edit: please no ridicule of any replies. I’m looking for personal, subjective opinions. Doesn’t matter if other people don’t agree. Thank you
