Maybe. Are humans and animals that special that some can conclusively say there are no aliens? Just thinking aloud.
Ya i am agree with you there is nothing like Aliens and only it is show in TV and in cartoons also just for entertainment.
Aliens, I believe are real, but they look exactly the same as us, the only reason we call them "aliens" is because we've never discovered them, and I believe that God has made it impossible to reach them, if there are Aliens.
I believe in them ... no one on earth believe or will believe .. they kidnapped me last year and took me to there planet .. aliens smell like hell .. :|
You can't prove that every single life form on this planet started here, so the alians maybe closer then you think! Theory has it that life infact didn't start here, and that it was carried here on meterorites in bacteria form.
