"evidence of life beyond Earth". I sometimes think GOD is/was actually an extraterrestrial body. It/He came to earth when humans were apes ( or simply say human were not that intelligent as this extraterrestrial body was ). At that time humans decided to call him almighty for obvious reasons. That was the seed for a theory about GOD. Later on humans created lots of religions and lots of imaginary GODs as per their convenience. ( Now we have enough GODs and religions to fight with. And discuss my GOD is better/powerful than yours. You will not goto 'heaven' ( some imaginary place or may be another planet ) if you will not follow my religion ).
