Why I have to believe in God

The more I look into the whole "Is there a God ?" thing I come up with the same conclusion. Evidence at this time points to maybe and to believe I must have faith. Why have faith when its easier not too. This is my reason:

Without a God then I have to assume that this whole 75 year long rant I call life is its own purpose. The point of being is nothing more then to be. More or less procreate, amass stuff and pass it on to my children in an effort to keep my genetic code going. If this is the case and I have no soul and that is the purpose then everyone that I precieve as less then me does not deserve to live.

The mentaly retarded children that are born in every family and on every continent are not important they are genetic offshoots that should be terminated because they weaken my species as a whole. There is not a prefectly good soul in those shells they are only ruined chunks of meat and if it came down to them and me I know that I could easily triumph over them. Stephen Hawking is supposedly one of the smartest men of our time and yet I know his giant head would only searve as a nice bowl on my mantle if it was survival of the fittes. So what the fuck is my point?

The fact that we progress is to me reason enough to believe in God. If we are only evolving then what changed 75,000 years ago that made us make the leap to conciousness from ape? I think that people are getting hung up on the physical evoloution of our species and not giving an educated look at the psychological evoloution that happened out of the blue for what seems to be no reason at all.

This may all seem to be a bit Psycho but I have been called worse by people with higher educations then whoever is going to read this.
