The Un-Original Sin

When two ultimate forces are spread out in the universe and both compete for same space, then they will have no choice but to share their existence across time, rather than space.

Thus any space in the presence of an near-omnipotent existential force, can only be occupied by one sample of this force.

In less abstract words, take homosapiens taking over the world as the dominant species, and evolution as the omnipotent force they possess in competition for life.
In our world, we don’t have any alternative powerful hominid species left. Our ancestors drove them extinct with help of external forces by evolution as well.
Only way homo sapiens can be replaced in the world at this point, will be by their own doing. A sentient powerful being overruling a finite space, becomes responsible for its eventual destruction, its demise. This is not a blame-seeking responsibility type of thing, but rather a promise, a prediction of the act of self-annihilation.
If you exist long enough, you will experience every combination of being, up until the one where you experience self-annihilation. As that is the cure for infinite existence in a finite space. As the popular songs remarkably puts it: “who wants to live forever?” (see mortiplicity post-credit scene”)
Now let’s expand this to space…
We are unable to observe any sentient aliens reaching for us… For an infinitely evolved sentient species perhaps, space becomes what the “world” is for us. A finite space where every one of your actions have an impact to whole space. Thus you become the sole potential reason/force for your total annihilation; the curse of power is that it brings total responsibility.

Considering we can’t observe any sentient species, can we then assume as we observed for homo sapiens in the world… That we are that sentient species for space? A species evolved in a space void of an omnipotent species. Only waiting for its million years to make their own mistake and reach for total annihilation of fabric of space…to let the time come for another sentient species to evolve alone and void of any remnants of the past, cleared by a universal mistake, the un-original sin.

The sin repeated by many generations of different sentient species, across time in same space.
