I believe that life outside of this planet, solar system, galaxy..local area group etc. whatever is a good possibility, but most ufo's, and alien abduction peeps are about as credible as flat earthers to me. There are intriguing stories out there for sure, but they all lack common denominators for the most part and always leave me skeptical.. I just watched a video on this supposed alien craft.. and as someone who's worked with military aerial camera payloads I agree with these guys at metabunk it's probably just a hot air balloon or something flying through the air. https://www.metabunk.org/threads/aguadilla-infrared-footage-of-ufos-hot-air-wedding-lanterns.8952/
UFO communities just get so ecstatic every time some grainy unanalyzable footage gets circulated..
