I don't know why you go down this rabbit hole about "denying the 'default' conclusion". There are no "default conclusions".
Normally the person who has the burden of proof is that person who makes the assertion. Like this: The burden is on you there. Be sure to explain how you constructed your probabilities. I'll present Brahman as the God:
In Hinduism, Brahman (/brəhmən/; ब्रह्मन्) connotes the highest Universal Principle, the Ultimate Reality in the universe.[1][2][3]In major schools of Hindu philosophy, it is the material, efficient, formal and final cause of all that exists.[2][4][5] It is the pervasive, genderless, infinite, eternal truth and bliss which does not change, yet is the cause of all changes.[1][6][7] Brahman as a metaphysical concept is the single binding unity behind the diversity in all that exists in the universe.[1][8]
