I like where you're going with this, but I think you need some caveats. We will inevitably get there if we survive long enough. So long as we don't destroy ourselves, a bigass rock doesn't plow into the planet(again), and we've left our solar system by the time the Sun decides to go super-nova, then yes, it does become inevitable. When we've got six or seven inhabited star systems, the odds of the human species dying out become negligible.The odds of Humanity colonizing the stars are almost inevitable.
The odds after that of humanity fabricating entire universes are just as inevitable.
Therefore the odds of us being part of such a fabrication are just as inevitable.
Do you realize that words are symbols just like numbers?
One plus one equals two is the same as 1+1=2
