Yes, ARITZIA is a feminine form of ERETZ, which is Hebrew for EARTH, and your account exists solely to talk about the EARTH.
You say you are a woman, which would explain exactly why you chose the female form of the Hebrew word for Earth instead of the male one.
Your story of ARYZIA actually being a combination of the name of two of your horses, Ary and Zia, sounds much less likely especially since you continue to claim your avatar is a painting of a flat earth when I've already proven it's a globe earth painting by St. Hildegard, who believed in a globe earth.
