I don't negate its existance, just relize its the explination and assumptions that differs, not the evidence itself.
Explanations might differ if each piece of evidence was interpreted only in regards to itself. However, the totality of the evidence points decidedly toward evolution and common descent. And there is a lot of evidence out there. A Scholar Google search turns up more than
3 million papers on evolution. There are millions more not available on line. Hundreds of thousands of researchers in numerous fields have been adding to this body of knowledge for more than a century. By dismissing all this as "mere assumptions" you are doing a disservice to the work these folks have labored over.
