Hi Udjat! The gnostic view on Evolution is covered in the Gnostic Wisdom course. Alot of the theory about evolution, how the universe evolved, what's our purpose here etc.. is covered in that course. But ultimately we can't really "know" these things until we can verify them ourselves, and then it becomes truth. Our own truth.
That's why the gnostics put a real big emphasis on the techniques and the practical aspects of spirituality. So we can learn these practices and use them as tools to find out the truth. Its better than saying to others "This is how the world works! Believe it! ...or youre not getting into heaven" etc...

All the best!
