Don't try and argue evolution versus god. Apples and oranges. Instead, argue that they can coexist and prove by contradiction that they can't. Allow me to try and explain:
Evolution is statistics at work over time. "Survival of the fittest" means that one species was more suited it's environment (which can be anything: human body, jungle, etc.) relative to another. If both species have the same resource requirements, this puts them in direct competition and accelerates the effect. If the species are not in competition, they are still affected by the environment. If species A, on average, makes 4 offspring via sexual reproduction (2 parents) and then the parents die, the species has made a net zero increase to their population. If species B always makes 4 offspring via asexual reproduction (1 parent) and the parent dies, the species has made a net +3 to their population. If A and B live in the same area and each member of both species require the same amount of space to live, species A will eventually die out unless it finds more space elsewhere. This will happen regardless of competition or predation because space is a basic requirement for all life. This is because, on average, B makes more offspring than A. B is outperforming A.
If you want a video game analogy: Red team has mostly newbie players but has some super-elite paid professional players; Blue team is composed entirely of regulars (not pros, but not newbies either). In a game of team deathmatch, Red team will have an equal or lower average kill/life ratio than Blue team. If enough games are played, statistically blue team will have more wins than red team.
If that doesn't make sense to you, go watch an episode of Deadliest Warrior and that may help.
No matter what god you believe in, creator, observer, or other, statistics exist because math exists (hopefully). Now, we might not know exactly the origin of life, but if a god created all life, he had to have pushed a start button somewhere. And unless he is hand-guiding all life in their physical and behavioral changes, it is statistics at work.
There are many, many more aspects to evolution than explained here, but essentially, evolution is statistics. Take a course or read about evolution and population genetics if you want to try and understand better.
Math. Tools of the Universe. Tools of God. But which one is wielding them? I don't know. Do you?
