Welcome to the board, Zeviander.
Isn't it interesting that having an awe-inspiring experience regarding the vastness of reality and feeling by comparison "utter insignificance" can lead one to recognizing the value in choosing to be the center and purpose of that universe!
That is very much what is meant in Satanism when we say that you choose yourself to be God. (You can read an elaboration of this idea in an essay I wrote here
regarding what Satanic atheism is and isn't in the Satanic Source Sheet).
So welcome to the center of your universe!
