We saw that the A Bomb test created (or allowed) Bob into this world.
Are we to assume that the same happened with Mike and that the A bomb allowed him earthly existence? Remember that Mike worked with Bob until the former found god.
Just a thought - we've not seen any backstory of Mike yet.
I guess... Is Mike one of the other eggs?
I think it's a big affirmative that the first atomic bomb test fully broke the boundries that prevented the BL, and the WL, from directly accessing this plane of existence.
Further garmonbozia to think about...after Trinity there were over 2000 nuclear tests done by the various nuclear powers, including over 200 in the continental US alone.
If the testing in New Mexico released/created BOB, were "more BOBs" released/created just after that in Japan?
