no one knows exactly what happened, or if it was premeditated or not at this point
but it is pretty obvious that Casey was responsible for Caylee's death
at some point logic and reason has to factor into the equation
she didn't report her child was missing,- fact
she acted quite normal during the time her daugther was "missing" -fact
she partied, shopped, got a tat etc etc -fact
she lied to LE who were there to help her find her missing daugther - fact
she made up people that didn't exist - fact
specifically she made up ZG, who she said took her daugher - fact
on the everning of the day her daughter went missing she is in blockbuster casually walking around with her boyfriend renting videos - fact
All of your points above only serve to show evidence that she was covering up the fact that Caylee was dead. It doesn't prove that she murdered her, or that it was intentional. We have to remember that throughout this period there was no kidnap story, only the 'Caylee with the nanny having fun' one. Her actions during this period only lose credibility once she changes her story to the kidnapping one. It is certainly callous and cowardly to conceal a death and act as though she hasn't a care in the world, but deceit is the tool she appears to use to deal with any 'problem', and IMO it's not unreasonable to assume that her cowardice and fear of blame after a fatal accident would lead her to take exactly the same path as she would if it was murder. Her behaviour suggests a cold heart but we don't know (and may never know) what she was really feeling. It's quite likely that she did not love Caylee as a daughter but more like a sister. CA seems to have placed herself in the role of Caylee's mother from 'day one' so that might explain the level of detachment, but the pictures of KC and Caylee together do show genuine mutual affection IMO.
item in her car point to a dead body being in there - fact
her own parents both admit that it smelled like a dead body, a former cop and a nurse who are familiar with that smell -fact
This evidence shows that there was a dead body in her car and that it was most likely Caylee, but again it doesn't prove murder.
I could go on and on
