We placed the wormhole there, but for us to get that far as a species to develop that technology we had already have had to make it successfully off the planet or to get that black hole data that the robot got.
So we had already made it without making it.
If we already made it without making it, we would not need to make it.
This is a quantum mechanical trick where the end defines the means. There are quantum mechanical events that take place all the time. The many-universe theory says that each of these triggers parallel universes for each of the outcomes.
So the only universes that contain human life beyond the point at which we should have gone extinct are those that have outlandish occurrences such as our 5th dimensional descendants rescuing ourselves with a wormhole.
It's like - why are physical parameters so perfectly tuned to allow life such as ours in the universe? These physical parameters could take on any value. According to quantum mechanics they are undefined until observed. Then the wave function collapses and it takes on a specific value. So who observed it? Maybe it was us? It could have been astronomers and physicists who made observations that retroactively collapsed the wave function for those parameters (QM really allows for this). If it requires an observation to take on a specific value, then by definition, the values the parameters take on must allow for life.
