If complex systems such as computers require the need of a designer to find both purpose and function it doesn't make logical sense to think that infinitely more complex systems such as the human body occurred without an intelligent agent.
And what of the infinitely more complex system that entails God? What would be the intelligent agency that allows for the complexity of that system?
To occur naturally, the wherewithal needed to be present and come together just for the hell of it
This is a contradiction in terms sir. To come together naturally is to do so without the addition of an external agency which is what you then imply by the phrase "the wherewithal needed".
