aliens and socks

i do not believe in Aliens but i saw that movie fourth kind and it freakewd me out about the whole alien concept (i suggest the movie if you like scary movies but im easily scared so you might think differently).. my sock never match but as of this moment im not wearing any socks cause i hate just walking around in socks it makes my feet feel closterphobic.... but as for the alien thing i dont believe there are any out there but im very courious as to if there any life forms or other plants like ours out there in the many solar systems that we will never know exsits..
