Well your biggest enemy is grammar; this would have sounded much better with fewer run-on's and wordy phrases. I don't know your age, your first language, or how long you spent on this (no need to tell if you don't want) but you'll want someone to read over your script before you add it to the images.
Outside of that, I see lots of potential in this prologue. You have a very flexible plot to work with. Clearly there is a fantasy theme here since you have machines breaking physics by creating something from nothing (Edward Elrich would be in tears right now).You have an interesting situation here: you can come up with some sort of explanation for how this is possible, but in the end the readers will have to possess some suspension of reality.
The mystery of what happened to the super mutants is a great secret that you can introduce at any time. I suggest you think carefully about the role this mystery will play in your plot; it should be substantial considering you mention it. A good idea is to leave it alone for a while and bring it back into relevance later in the plot.
The mutant concept is useful because you have free reign to create countless original characters. I'll be interested to see what kinds of bizzare characters you devise.
Lastly, you have what every manga needs: a conflict/problem. In this case, it's the mutant-vs-human problem.
