Am I still valid as a therian even though I don't believe in past lives?

Hello. My name is Sandra. I am here to ask a question about whether I am still valid as a therian even though I don't relate to having a past life as my theriotype. So, for context, I don't believe in past lives. It might be because I am Christian, and in Christianity, there is nothing about past lives. For me, being therian is more of a spiritual connection with my theriotype. I am a dog therian, more specifically a Bernese Mountain Dog therian, and I feel a spiritual connection with the breed as well as with nature. I don't know how to describe it otherwise. I guess it's like a spirit animal for me that I feel spiritually connected with. Most therians believe that they were their theriotype in their past lives, and I just don't relate to that. I believe that the life that I am living right now is my first life and my only life on this Earth. I am just wondering if my experience, being different from most of the community, is still valid and if I am still a therian even though I don't believe in the past lives part.
