Aliens- Into the Mind of Aliens

Yup, I believe in aliens. I believe in them, but don't believe in UFOs. What type of aliens do I believe in you ask? The scientific type, the ones that are on alpha centauri. The ones that are so inhuman that it's hard to imagine them. Thats the type of aliens I believe in! why don't I believe in UFOs? Well, UFOs are just lightning, sprites (electric discharges), chinese lanterns or experimental aircraft. If there are intelligent life their probably ahead of us. Why? What makes us as intelligent and amazing as we are is partly because of the food we eat, if other planets have higher energy levels than earth and if aliens can eat the energy levels their brains will have higher energy levels then are brains making them more intelligent, but if the planet is a cold one or normal one they could either be stupid or at our level. Communication with aliens is another story. They live on a totally different planet and have a different way of living, eating communication and etc. Also their brains could work totally different creating a huge communication gap, but if they live on a planet with high energy levels their brains will be more advanced and be able to possibly find a way to communicate if they haven't already. So thats my theory on the alien brain!
