> it becomes easy to deduce that based on point 2, switch was not human induced

This just isn’t correct at all. The evidence isn’t conclusive but if a human operated switch was flipped, and one of the humans present says to the other one hey why did you do that, then Ockham’s razor points to a human flipping the switch.

It’s not the only option, but it’s certainly the most likely.
