No one disputes micro-evolution -- variations within species. The dispute is over macro-evolution, where a fruit fly becomes, through small changes over time, a human being, or at least something entirely different than a fruit fly.. Sounds ridiculous, but that IS EXACTLY what evolution teaches.
The theory of evolution does not state that insects evolved into humans. That is just not how it works. It DOES state that all life has a common ancestor in the distant past.
Tell me what is the difference in so called "micro and macro" evolution? There is NONE! If you accept micro-evolution then you have no problem with the basic tenets of the Theory of Evolution.
