Does Atheism Lead to Nihilism?

Intrinsic value proponents would claim that there are objects that cause people to value them unconditionally, for example acts that produce more pleasure cause us to value them unconditionally. I don't know how we would be able to know that. Most arguments given are based heavily on intuitions and thought experiments which are nothing to write home about. However, most of the time moral realists aren't clear as to what intrinsic value is, will disagree greatly over what has intrinsic value, and even over what "intrinsic value" means.
Personally I don't see what the big deal about intrinsic value would be. Intrinsic value doesn't resolve moral disputes; So, in terms of practically it doesn't make difference.
