That is not true, If you look at the evidence and determine that the purpose of the universe is to produce a being who is able to understand the universe, which is the strong anthropic theory, then evolution is not random.
Another view is that the purpose of evolution is to maximize unity and diversity of life.
While I would say that philosophically these views point to the existence of God, they do not per se require one to believe in God. They are a matter of fact rather than a matter of belief.
God does not guide the wind, but God sets up a rational structure or laws which guide the flow of air, so that our environment works in ways that benefit us and the rest of Life.
Rationality is the ability to think, but it is also the product of thought. People are rational unless they do not use their minds rationally. Processes are rational when they exhibit that they are rationally structured. Nature is rationally structured, while there are instances when humans and human systems are not.
