Do you Believe?

I believe in God. I have made an investigation before coming here though. I don't just want to say what I think. I want to know why others don't believe in God. This is why

Humans are one of the most flawed creatures in existence. One of the major problems with us is bitterness. The wanting of what others have. People have died because of this foolish desire. Allmost every emothion revolves around this feeling. Hatred is created because you want what others have.
Another is ego. Not being as rich, pretty or smart as a person makes us feel a great resentment. I know people who are smarter than somebody in any way causes the less able person to force their brains to believe that the intelligent person is less then them in many ways.
What does all this have to do with belief? I'll tell you. In my theory there is two types of nonbelievers.. One is the jealous type and another is the resentful type. Here they are

Jealous
These people are jealous that there's something that they'll never know. God is something that man will probably never have proof of. These people have little faith.. They need to know if he exists or not. Not knowing makes them frustrated so they cast aside all belief.

Ego
Then there are the egotistical. These people pride themselves on knowing everything. Being good at something gives them a sense of joy and peace. There ego is shattered however when they find out that they will never know if they will go to Heaven or Hell. They fear what they do not know and thus they will their minds and souls to stop believing in such things as the afterlife or God.

I think this makes sense. I have school during the day so don't expect me to reply to any of your posts until 8 PM at latest.
