I'm not sure what you mean. An "original" Earth before any quantum wave function collapse? Could you elaborate a little bit more please

I don't understand much big boy talk but I'll put it simply
But this may resemble an episode of Avengers
If we destroy our earth than any earths parallel to it would also be destroyed but reality would still exist.
If we destroy earth prime ALL of the parallel universes would be destroyed because that was the "original" earth. Every other earth was just a variation of it.
The question is, does that earth exist or is it only possible in theory
