Earth Giants

Earth giants live in quicksand patches in the furthest reaches of the desert. They're almost impossible to study, because they are most active when the sun is at its hottest. As soon as the temperature starts to drop, they retreat to their quicksand homes and disappear into them.
Little is actually known about them. No one even knows how big their population is. But it's commonly believed that they live and die alone. NO one has ever seen two Earth giants together.
There is much debate about the origin of this species. Creationists believe that God created a set number of Earth giants. Some say it's 2200. Others say it's a lot lower than that...about 69 at best.
Evolutionists believe that Earth giants evolved from a combination of irradiated desert sand and cosmic space dust. They say that there was a slow progression of evolutionary steps from the first saharianic petrachlors to the modern petra giganthropes.
There has been evidence in the fossil record that Earth giants used to live in Alaska. No one knows how or why.
It is unknown what Earth giants eat or if they eat at all. It is speculated that they absorb minerals from the quicksand they live in. And the quicksand helps them grow. But again, this is all just speculation. No one has observed an Earth giant eat. Perhaps they don't eat at all. That is a possibility too. Just as there are desert animals that live only on the smallest bit of morning dew. Perhaps Earth giants function the same way.
Also unknown is how/if they bear offspring. The popular belief is that they reproduce asexually, forming buds and knots that fall off and turn into immature Earth giants. But no one has ever seen an immature Earth giant, much less a baby one. So, the answer to this question is like many other questions regarding this species: It's all up for debate. 
Perhaps the full truth will never be known.
