How does that relate to everything being creepy? Somethings are creepy, most are not. As to the bugs... it probably stems from the fact that evolutionary-wise it would make sense to keep bugs off of you. Bites can be venomous or become infected or at the very least cause discomfort.
I made a fire pit kind of like that out of logs at Camp one year we put a massive amount of kindling in the center and let the sucker. Had a fire for 6 hours plus
