Is it true that education without god is not a education?

That statement is a matter of opinion and faith, not a universally accepted fact. Many people believe a strong moral and ethical framework is essential for a complete education, and some find that framework in their religious faith. However, others find it in secular humanist principles, or other belief systems. A good education, in the eyes of many, encompasses critical thinking, problem-solving, knowledge acquisition across various disciplines, and the development of well-rounded individuals, regardless of their religious beliefs or lack thereof. Whether or not a specific religious perspective is incorporated into the curriculum is a matter of differing viewpoints and educational philosophies.
