The greatest doctor to ever live used ocean water as the only cure, he would inject pure ocean water into the veins and babies and old alike restored to health in a few weeks like a miracle. he used pictures of every patient to prove it.
In war time the USA Navy medical ships used ocean water in place of blood.
Ancient history talks of humans/fish, many cars carry the fish symbol on the back, wonder if they really know what that symbol means! God created us all, fish, humans, animals, etc. all that depends on blood for life are closely related. We just happen to share blood very close to the fish and that makes people wonder!
