I don't get some people. Like you people. Why can't anyone in this world ever appreciate that God created us in his image; created us alone. Being created in the image of a God, why would anyone think anything could ever bring us down except each other? And for that matter, Why would God make more than what He has?
Here, I've even got scriptural evidence that supports my theory of there being no aliens:
Genesis 3:20:
"... And Adam called his wife's name Eve, because she was the MOTHER OF ALL LIVING"
Believe what you like, but I believe this to be the truth; that because she was the mother of all living, that the only living things in existence always have and always will reside on this little blue planet.
Not to mention, that God speaks of only this earth in great detail during creation, and individually created the earth, the plants, the animals, birds, etc, and finally man, in the greatest detail of all.
So basically, if you spend your life worrying about aliens or hoping someday we will "make contact", I am undoubtedly going to say that you are wasting your time, your life, and anything else that makes you human.
