Once again, you're misinformed and you're still being extremely rude to preach about how science works. I'd be positively shocked if you have as much of a background in the hard sciences as I do. Setting your implications about my ignorance aside for the moment, I'll share some supporting research:
A 2010 systematic review found that most studies suggest spinal manipulation achieves equivalent or superior improvement in low back pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up.
Dagenais S, Gay RE, Tricco AC, Freeman MD, Mayer JM (2010). "NASS Contemporary Concepts in Spine Care: Spinal manipulation therapy for acute low back pain".
Many, many other citations of relevant research can be found at
