When the Space Age as about, the U.S was developing satellites, they were using a radio signal satellite to search space for planets. These satellites not detect waves. They came across a highly spinning object. Scientists were baffled as something supposedly should not be able to spin that fast. It started as a joke, but it evolved into more, it was dubbed little "green men". That as when the idea of extraterrestrials was first scientifically concidered. It ended up being a star that was forming.
"Beilive" is wrongly spelt. It is "believe". If you can't spell that correctly, how will you believe if it is proved that aliens do exist?
Edit- This person obviously wanted a serious answer and then you start commenting on his spelling when you can't fix your own grammar? 'wrongly spelt' It's incorrectly spelt.
