English to Arabic Science Science (general) Theory of Evolution

How would you translate this clause(it's a bit confusing)?: in their argument in favor of single-burst creation over the theory of evolution.

They outright reject evolution without attempting to understand it. In their argument in favor of single-burst creation over the theory of evolution, they sometimes present a distorted version of the theory and then respond with arguments that are based on their misunderstanding and not on what the theory of evolution presents. This makes it confusing from beginning to end.
