I believe in evolution, and maybe some type of intelligent design, sort of.
Evolution is proven, without a doubt, scientifically. Anyone who says different has some sort of lack of true information, and/or clouded with the truth they believe is religion. I am not saying religion is wrong, any religion, and I won't know for certain until I die, but evolution has been proven. People have observed changes in species, specimen, over time. I sincerely encourage everyone to read up on some Darwin. Darwin is not the devil, as some people like to assume. That's all I'm going to say, just read some Darwin and read about what he reall did, who he really was. You will see, without a doubt, that the religious media portrays him extremely terribly. Now, that said, I do not mean evolution from a common ancestor of apes a long time ago to form humans and present day apes. But those who thing humans evolved from apes, you are 100% wrong. Humans did not evolve from apes. What the evolutionary theory states is that a long time ago, apes and humans shared a common ancestor, and through random mutations, that common ancestor evolved into two completely different species. One of those species being apes, the other species being human.
I am not saying I believe that 100%, as there isn't enough information for me to believe that 100%, though I do believe that to an extent.
I honestly don't care where humans came from, that doesn't interest me, but I do not believe some mighty being just poofed us into existence. So yes, I believe evolution, mainly because it has been scientifically proven.
As for the intelligent designer thing. No I don't believe we were poofed into existence suddenly, I believe we evolved from something, a long time ago and evolved over time, but I semi-believe that the universe, that everything in existence has two possibilities.
1) Some sort of being suddenly burst the universe into existence, somehow, and then left it alone to grow.
2) Nothing exists, and because of the absolute nothingness, reality was born. I know that sounds bizarrely insane, and I don't expect anyone else to understand what I mean and I don't even know how to begin to explain it more.
And that's what I believe.
tl;dr
I believe in evolution, and those that do not should give some of their time and research it more, read up on it more. Especially read Darwin, Darwin is not the devil and is much better than religious media portrays him.
I do not believe humans were just suddenly thrust into existence, but I semi-believe the world, the universe as we know it did have a small amount of help in forming do to some higher being.
