Howling:Were the Daleks and Cybermen aware of the cracks erasing their events?

With the Daleks and Cybermen being the "big guys" of the Alliance, and their knowledge of the cracks, I link it to the fact that the two known erased events involved them. I'm guessing at some point, the Daleks became aware that their stolen Earth invasion had been erase from history, and they rememembered their precedeors involvment due to being time travelers. But I am more confused about the Cybermen. The Cybermen, who fell through the void to Victorian London, would have been erased with the cracks, right? I personally believe the former invasion was prevent by the cracks erasing all of the Dalek ships, or erasing Dalek Caan to prevent him from causing the invasion. But I'm confused with the Cybermen. I might guess that when the event was erased, they no longer got destroyed during The Next Doctor.

Oh, the crack confuses the hell out of me. Delton Menace 04:26, June 24, 2010 (UTC)

I personally think that these cybermen were a different group to the next doctor boys. As when you think the ones in the next doctor fell out of the void considering how many were in the void its not so unbelievable that another little group would have fallen out, and gone some where different, they could have stolen Dalek tech too, maybe they got wind of the cyberking invasion and it being erased and paniced. As for the Daleks it well I do definetly agree that they would have been made aware due their past being erased, as for how they could have survived with their past being erased well any number of reasons like what has been posted on this wiki.
