I attributed motive to Hawking's model based upon Hawking's own words in the lecture which is linked above.

No one is accounting for the ultimate cause of existence, but if spacetime does not require a singularity, then it does not require a singularity

It is imaginary space/time which Hawking suggests does not contain singularities. Real space/time still requires a beginning.

What should have been the object of the model is a rebuttal to the loss of information in singularities. This has been a big problem all along for those trying to account for the origin of the incredibly convenient physical laws and physical constants. In the lecture, Hawking goes far afield of this goal and addresses directly the belief in a Creator.
