First, the assumption that the genetic makeup is really "very close", may be a fallacy. (Link - Answers In Genesis, "Greater than 98% Chimp/human DNA similarity? Not any more" by David A. DeWitt, Ph.D., Department of Biology, Liberty University)
Whether humans and chimps are close genetically or not does not demonstrate the necessity for a common ancester. Humans and bananas share approximately 50% of the same genes (Creation Magazine, 24, pp. 10-12, 2002). Does this make make half banana? I believe any commonality lies in the fact of having a common Creator. To accept the DNA molecule as being the result (effect) of time & chance (cause) is beyond my understanding.
I believe that it is important to understand that "evidence" is relative to the credibility (or faith) one puts in the source of the information coupled with ones' personal world view.
I propose that all humans "...walk by faith" (2 Corinthians 5:7), as we are not omniscient beings and thereby determine what is or is not true based upon where we have placed our faith. However, I do not believe that truth is relative to ones' perception and do believe that a finite (in knowledge) being can determine beyond a reasonable doubt absolute truth.
