The other part of the inspiration came from finding in my research that once upon a time homo sapiens was not the only human on the planet. It is now, all of the others having died out. But there was a period when two types of humans were on the planet at the same time, Homo floresiensis, nicknamed "the hobbit" due to its diminutive stature after it was discovered in 2003, and homo heidelbergenis, a species called of all things, "Goliath" because of its great height.

I thought, wow. When these two humans shared the planet, did they recognize each other as the same creature, basically, but just different species? Or were they like the alligator and the crocodile who, scientists believe, don't recognize each other at all as they swim past each other in that rare locale that finds itself home to them both? Or were they like the great apes and monkeys, where one considers the other little more than food, though descended from a common ancestor? This idea of hobbit and Goliath came at the right time.
