Question about Cybertron origins (may be spoilers!)

ok, so, the thing that i find terribly interesting about the Allspark is that it turns mechanical and electrical things into life. we see it done to several things in the movie...
so, what I'm curious about...... is it possible that, for the movie continuity, Cybertron originally housed a long-gone civilization when the Allspark arrived, giving life to all the technology that outlived its creators?
