Judeo-Christian theology and atheistic evolution as taught in schools are incompatible, to believe in one requires an absence of belief in the other.
Darwinistic evolutionary explanations of how life arrived on earth don’t even rise to the level of lies, they are nonsense. How do you ever get any fittest in order for them to survive? In an environment when almost all things that could happen to alter the makeup of creatures is harmful, not helpful? The answer if even attempted is on a par with “It’s turtles all the way down.”
If you want a reason that something was created, you look for a creator.
Judeo-Christian theology and atheistic anything are, by definition, incompatible.
