For me, the layperson, what is the standard? With a lack of direct physical evidence - when there is no gun with fingerprints, no video surveillance tape, and no handwritten confession - is the key for the accused to just to deny, deny, deny?
Means: snapping the neck of an adult isn't that difficult - if you know what you're doing and your victim is asleep or unable to fight back, the cervical spine of an adult can be broken without great strength - so, the neck of a two year-old would be easy. Likewise, suffocating or drowning a 2-year-old would be easy.
Motive: Much like South Carolina's Susan Smith, I would argue that she didn't want to be a mom because it was getting in the way of her partying and potential romantic hook-ups.
Opportunity: The baby was living in her house.
So, in sum:
1. Internet searches for chloroform; neck breaking.
2. Baby missing for 31 days and no report made. When questioned, Casey said, “The nanny took her.” She later admitted that she had lied and wanted to “keep her job at Universal Studios” (which was also a lie – she did not have a job at Universal).
3. She was reportedly not upset or distraught during the time her baby was "missing". Instead, she partied, went shopping, and got a tattoo that said, "Bella Vita" (the good life) and moved in with her boyfriend:

4. The smell of human decay was so strong in Anthony’s car, that the grandmother said that she had to use ‘Clorox wipes and Febreze on Caylee’s favorite doll to get the smell off’ – this favorite doll was found in Casey’s car, along with strands of the baby’s hair in the trunk with more ‘rot’ smell.

5. Casey Anthony had abandoned the car with the rot smell where the doll was found. Casey was not a woman of great financial means. She did not have money to abandon a car she could not afford to replace (which was a newer model Pontiac ). Also left in the car was a pair of Casey’s shoes and pair of boots.

6. Sometime after the baby went “missing,” Casey asked to borrow a shovel from a neighbor. It was still in her house when police searched.
7. This photo was taken at a “Hot Body” contest Casey entered after her baby went “missing”:
