"The earth and everything in it, the stars and the skies, and humans. Everything is created..but from what?"
Well all of those things are composed of matter, except for the "skies." The skies is to vague to define. From what I've heard some models in physics suggest that all matter is in fact a form energy. I also disagree with your use of the colloquial term "created" I believe it misrepresents the facts of the matter by implicitly implying that it was all consciously created with intent.
"Evolutionists talk about the big bang theory but they always fail to address the issue about what initiated the big bang." Evolutionists" do not exist, that is a term used mainly by religious apologists who created it to mean anyone who believes or speaks about anything that involves the word "evolution" which means to change over time. This term refers to a wide variety of people and experts in multiple separate fields.
Molecular Biologists, virologists, pathologists, anthropologists, geologists, etc. do not discuss the big bang, cosmologists, astrophysicists, and to some degree quantum physicists discuss the big bang. And they don't fail to address it, the official position of the scientific community at this time is: We cannot say with any reasonable degree of certainty what caused the big bang. The reason this is said is because of the intellectual honesty to not assert what cannot be supported.
No one knows what caused the "singularity," as it is sometimes called, to expand into what we now call the universe. The reason we can't really say is because our knowledge of physics only applies once the universe exists (the moment following the big bang).
