What do atheists believe about creation?
THere isn’t a proper answer to this; the only thing “atheists” have in common is that they do not believe in God (or gods) and therefore do not believe the universe was created by a god. Atheists as a group are defined by what they DON’T believe, rather than by what they believe, so there is no particular consensus. True, a great many subscribe to the big bang theory, followed by evolution in one form or another. Others believe that the universe has always existed. Many others readily admit that they don’t know how the universe was created, and don’t believe that anyone will ever know. Others have unique theories all of there own. It’s important to remember that Atheism is not a doctrine in itself, but a term describing absence of a specific doctrine.
Every theory proposed by atheists has required a beginning of some form. The big bang theory requires a source for the densly packed sand particles that led to the explosion (besides the fact that no other explosion in history has ever led to a creative force. Explosions, by their nature, only lead to destruction). Evolution requires something to evolve from (eventually, if you go far enough back something had to evolve from nothing). Even string theory requires an origin for the strings. Interestingly, string theory actually raises more questions than it solves because it creates several universes even though we can’t see them, meaning the creation debate has to be answered for several universes, instead of just ours. The only theory that does not requires a beginning is that our universe has simply always been here. Of course this theory is illogical because everything we see has a point of origin. For example, babies and animals are born daily, and plants sprout into existence daily
