It is not incompatible with my belief system. I prefer the terms angels, demons, and gods when describing multidimensional entities, but the term extraterrestrials is not incorrect. I consider myself an angelic/demonic entity in a human incarnation. I would not find it implausible that there are other multidimensional beings (incarnate as humans) who may be of extraterrestrial origin. The main distinction I would make between myself and them is that I did not originate on any particular planet or other physical location in the universe, but from a nonphysical dimension, be it called Heaven or Hell. (This is my first fleshly incarnation anywhere. I have past "life" memories of existing with others like myself in angelic/demonic form in this other dimension. After I am done here, I shall once again assume angelic/demonic form and have no plans for further physical incarnations. Walking instead of flying or teleporting, catching colds, and the physical aging process leave much to be desired .)
