Do Aliens exist?

I've always been fascinated with unusual or weird things; whether it be creatures, human lifestyles or behavior or even events. Ever since a kid I enjoyed watching anything about supernatural stuff. But the topic that has been foremost on my mind is whether alien lifeforms really exist or not.
I always liked to imagine how it will be if I lived in an entirely different world -very unlike this one. Only few galaxies are known to man and therefore only a few planets. If God made other beings apart from us such as angels couldn't these beings exist? WHO REALLY KNOWS WHAT IS OUT THERE? I remember watching many documentaries in which persons actually claimed to have seen such beings. For example there was a documentary about 62 school children in Zimbabwe that said that they saw alien beings. It began with the viewing of a meteor by thousands of Africans after-which these children spoke about the encounters they had with these strange beings.



Many persons say well this is just a hoax or they may find it stupid while others stand firm on their beliefs that yes! they do exist and there are many eyewitnesses of the phenomenon of UFOs. Persons have even said that they have been abducted by aliens ...yet some professionals try to explain this as a mere sleep disorder.
It seems pretty puzzling to me ..don't you think? I mean why would people just go around lying about these little oval headed green creatures with large shiny black eyes? What's your view? Is there even the slightest possibility that they exist or are we trying to bring something to life that we ourselves have created in our minds?
