Who agrees with me and this theory?

Does anyone believe that God was made up in an effort to save ourselves from the unknown? This has been a topic with me and my friends at school. BTW, we're all 13. I mean, there has to have been some sort of creator, but that doesn't necessarily mean that it was a physical (or spiritual) being. All that we know was probably created through chemical reactions. And, although the Bible doesn't mention it, there is definite proof of evolution, no matter what any religious person says. Also another thing that is stupid but commonly said; dinosaurs were put in the ground to test your belief in God. Honestly, I don't think Adam and Eve would have gone to all that trouble. Another thing I find hard to believe is that people follow the Bible like it is a whole story of the Earth. Never once does it make reference to Africans. Only does it mention Whites and all that the Whites have conquered. It's scientifically proven that we all are descendants of Africans. Obviously, this was eons ago, but there is a trace amount of African blood in us. Over time, the human race has adapted to the climates and habitats the original Homoscapions (???) migrated to. The Bible has been changed by so many people, it probably doesn't look anything like the original. It also contradicts itself by saying "Man shall be with woman" and "All of God's children loved equally." I get teased, alongside my friends, because of this (people also throw in a few Bi-polar, OCD, and ADHD remarks, too). I wanted to know who agrees with all this, and who has their own ideas.
