tons of google links of doubts about the big bang and even cosmic microwave background...

even ICR themselves refutes or casts doubts on big bang using secular sources:
dust can emit microwaves that mimic this polarization pattern, and it is possible that this dust is responsible for most (if not all) of this signal. The BICEP2 scientists had considered this possibility in their analysis, but concluded, based upon a map of this “galactic foreground” microwave radiation, that the effect would be negligible. But it appears that they failed to consider the fact that this radiation map may have also included an un-polarized “haze” from other galaxies. This haze caused them to underestimate the true amount of polarization in microwaves from within our own galaxy, which in turn apparently caused them to overestimate the strength of the polarization signal that supposedly resulted from inflation.
That article isn't one of them, so try something else.
That article only questions whether what appears to be proof of inflation is really an artifact of something else. It does not question inflation in particular, and certainly does not question the Big Bang; it is an entirely empirical discussion.
