If the TWINS were not at their creche Thursday morning why did the McCanns LIE and what were they doing between 9am and 12.30PM?

As can be seen in the video below, there were huge discrepancies and/or confusion about who picked up Madeleine...and also the TWINS... According to the PJ Diagram of \events it appears that the twins only went in the AFTERNOON and not the morning! This would explain why Kate and Gerry could not get their story straight about picking up the twins... Many of us also believe that Maddie was not at the creche either so that leaves us wondering, did they LIE about taking and picking up ...
