Dr. Craig is a liar.

[Jehanne]

This is NOT the viewpoint of modern physicists and/or cosmologists who hold to actual infinities being a physical possibility.  Both Craig and you are wrong on this point.  You can listen to Sean Carroll discuss actual infinities, both in space and in time, right here:

The mathematical meaning of the term "actual" in actual infinity is synonymous with definite, completed, extended or existential,[1] but not to be mistaken for physically existing. The question of whether natural or real numbers form definite sets is therefore independent of the question of whether infinite things exist physically in nature. https://en.wikipedia.org/wiki/Actual_infinity 

Are you saying that physicists believe there to be actual infinite quantities of anything (objects or events) in the physical world?

Yes.
