Yep... That is what I’m thinking.. Bait and Switch..
I dunno. We know from Kara being a Cylon that it’s the Cylons’ earth. However it could also be the humans’ earth if you consider the Cylons were already amongst them when the planet was destroyed. Maybe it was a Terminator-style cyborg attack which sent humanity fleeing before earth’s destruction and ‘skin jobs’ fled along with them. The skin jobs waited 2000 years for humans to develop technology by which they could return to earth. The Cylons have always been predatory to humans in the series so they needed a reason to make humans flee the colonies and head back to earth to be able to return themselves.
