Two things to deconstruct here:
1) The term "kind" has no biological relevance. Furthermore, extant species do not evolve into one another (so no, a modern bacteria would not evolve into a amoeba). I suspect this is a misconception of the process of evolution due to unfamiliarity with the science involved.
2) You've already coming up with rationalizations to dismiss anything you don't want to look at by invoking arbitrary criteria by which you are apparently judging science. Even though it's clearly apparent you don't understand how science works, as is evidenced by your continued usage of the word "prove" in the context of scientific inquiry.
If you had an honest interest in learning about the Theory of Evolution and the evidence which supports it, I have an entire thread dedicated to that with various free courses full of information:
Educational resources for learning about biology and evolution
Though I suspect that you will elect not to take advantage of such resources. Such has been my experience with creationists.
