Did anyone else hear about the Pleiadians?

Yeah so I've always been interested in aliens and outerspace and looked into what "starseeds" were and all but it seems I keep finding the same information repeatedly on every site I see. There's the reptilians, alien greys, and always the pleiadians, sirians, arcturians and such. And also the Galactic Federation always comes up. Now I'm a pretty open-minded individual and am not one to brush off a strange concept that seems to our primitive brains highly unlikely for that sole reason. So I wonder if there is any underlying truth in this since much of it makes sense to me. I'm not saying I believe it I'm just taking these things into consideration as I do with all things presented to me. So what are your ideas on all of this? If you don't agree there is no reason to say it in a rude way, you can just say you disagree and explain why you feel that way. I respect all opinions so feel free to say what you believe.
