Hard to say though, since you never made any such attempt.
I am attempting but you seem ridiculously abrassive about asking questions.
1) the impact causes continental drift
2) the impact causes the Pacific basin
3) the impact creates the Pacific ring of fire
4) the impact raises the ring of mountains around the Pacific
5) the impact creates the Himalayas
6) the impact takes continental crust that completely covers the planet PreEarth and distributes it in patchwork fashion over the surface of the Earth
I don't see any of that being excluded from the big impact hypothesis it really doesn't drill into that level. So if you like my layman view is your theory is a more specific version of the big impact theory .... No or am I being dumb here?
7) Mansfield's impact does not claim to create the Moon.
Now I agree that is a big difference even to me?
So under this theory the moon was a normal orbital body capture method?
