Theories of Cosmological Origins: Are They Science?

I am intrigued by this. If true I did not know this. Did they also predict this in specific measurable terms or just predict it's existence?Do you have any more info on this?

ICANT can you see why the prediction of a specific measurable value for the CMB derived as a logical consequence of BB theory has resulted in BB theory being considered so much more compelling than other possible explanations?Can you see why the experimental/observational confirmation of a theoretically predicted phenomenon including an actual confirmed specific measurable value puts the theory under cnsideration into the 'almost certainly true' category?Can you see how unlikely it would be to have just guessed or randomly struck lucky with respect to such a result?How can you not consider the measured level of CMB as verification of BB theory?
