Since you posted the reference to Baalbek, I assumed you were somewhat familiar with its history. To quote from the Catholic Encyclopedia:
Among the monuments of Baalbek were three temples: the Great Temple of Jupiter, the Temple of the Sun, and the Circular Temple of Venus; all of them date from the second century A. D.
I suppose it is faintly possible that the giant stones you refer to were already standing and the rest of the temple was built around them, but that seems fairly unlikely.
BTW, do you know how these stones compare in weight to the obelisks which were routinely moved and raised by the Eguptians?
Assuming the temple actually dates from AD times, that's about the ONLY explaination

Not even close.
