This thread is dumb
evolution doesn't explain the origin of the universe, nor the origin of life even. Only how the very first simple life forms evolved in complexity and diversified to fill every available food niche in the environment. Thats all it is. There is an unutilized food source somewhere, an animal will eventually evolve to fill that gap. Predator and prey provide evolutionary stimulus to eachother via natural selection, the weakest prey and predators do not survive. The most "fit" for that environment, and the one whose genes lead him to be successful in reproduction the most times wins. His genes spread, and eventually the entire species carries the beneficial genes of its strongest and most promiscuous members. Its that simple for the most part. You don't have to believe, read some books, it is all explained already.
Disclaimer: There is nothing in the theory of evolution that disproves god, and they need not be mutually exclusive. Believe god was the cause if you so choose, but evolution is the "how" no matter what way you want to look at it. You can believe in both.
Also the big bang doesn't explain and is not supposed to, the cause of the expansion, only what happened afterwards that lead the universe to be what it is today. There was a tremendous release of energy, that we know. This energy formed the simplest, lightest elements on the table, hydrogen and helium. These two gases condensed in various places due to their own gravity, and formed stars. In the core of stars, heavy elements were born due to the tremendous heat and pressure crushing elementary particles together. Further down the period table, even heavier elements were created when these stars went supernova, the explosion cast these heavy elements, carbon, iron, nitrogen etc. etc. out into the universe. This "star dust" collected to form rocky planets, earth, and eventually You. We are all made of elemental particles created in a supernova, probably many billions of years ago. Thats kinda cool if you ask me![]()
FINALLY, someone gets it.
