What’s the differrence between atheism and evolution?

Atheism simply means you have no belief in any Gods. Just like theism means you believe in a God-- they are not religions. They are simply opinions on whether there is a God or not.

Evolution is a scientific theory regarding how life evolved and adapted on this planet. A scientific theory is not a guess-- it's a collection of facts that support a greater understanding of something.

You can be an atheist and believe aliens planted people here, or you can be an atheist and believe that evolution is wrong.

Of course, since evolution has pretty much a mountain of evidence supporting it, if you don't belong to a religion with an agenda to 'prove' ancient scriptures, then there's no need to deny it.

Plenty of religious people (even Christian denominations) accept evolution-- you don't have to be an atheist.

Atheism is about what a person believes about god/dresses...evolution is about the change all life forms have gone through since the earth was formed.
Even though most people who are atheistic accept evolution, they don't really have anything to do with each other. 

That's like asking what the difference is between girls and physics.

Evolution is biological science and is accepted by all scientists, both theist and atheist, who have taken the trouble to study it. Science has nothing whatsoever to do with atheism and atheism has nothing to do with science. Evolution is not a belief system it is a scientific fact with overwhelming evidence to support it. The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. The Theory of Evolution is the model that explains how the fact of evolution works.

Yeah, and all atheists believe 2+2=4. They're just brainwashed.
