>>12366163Actually, from what I understand, MWI basically does say that you're billions of years old.
I think MWI proponents argue that you more or less always existed in the fabric of the universe (for lack of a better way of putting it) but you didn't come into physical existence until whenever you were born. Basically, your existence was inevitable ever since the Big Bang, so you kind of always existed. And, just like your existence was inevitable, you also can't control much of any of what you do.
I know it sounds like retarded determinist religious beliefs, but that's because MWI basically is retarded determinist religious beliefs. I think it's really embarrassing that this pseudoscience has somehow gained respectability for the last 30 years or so.
