[Serious] Experiences with Extraterrestrials?

Hey, so...I'm curious.

Let me preface this by saying I'm a bit of a skeptic. I don't currently believe that aliens have contacted earth in any way, but I'm definitely open to the idea and can be convinced. I'm wondering If anyone here has seen an alien. Not a UFO, not a picture, but an actual extraterrestrial being. I don't mind if you don't have images; I just want to hear your experiences.
