Yes we are not alone. in fact we are just aliens too! We just call us humans. Aliens are some speciels in this univers and well,we are one. Belive it or not,we have "aliens" undere us. Hybrid humans called Reptiloiden. They rule the world and most of them hiding in switzerland. u only can see it in here eyes sometimes for some milliseconds. they can change it to a scarry form. there are thousands of alien races and some are visiting us all the time. i start believe in it after seen some "mothership" hiding in some clouds. it was so scarry for me and there was absolutly no sound at all. Yes,there are aliens and i am 100% sure.
