The gods have to learn how to imitate humans. It's a process. They first observe from a far and take on a guess of what humans look like. It's when they get there and see humans up close that they can smooth it out and perfect the appearance.
Even then, they fall short. Apollo hasn't thought to imitate a pulse until very recently when cuddling with Aseil and feeling his heart beat. Aktal hasn't cared to figure out how to imitate breathing. So he doesn't.
